Professor George Palade’s elegant experiment to follow protein synthesis and trafficking, published nearly 60 years ago, provided us with a great deal of information and has been used as a tool by several investigators. If you had access to all the reagents needed to repeat the in vitro experiment, describe what you would need to do to see the progression of newly synthesized proteins and their transport in the cell.
Answer:
The interpretation including its particular topic is demonstrated in the following portion on the interpretation.
Explanation:
After experiments with Guinea Pigs, Palade transitioned to anything in vitro research in which sections of pancreatic tissue had all been subjected to a pulsed radioactive lysine for something like a shorter amount of time. The radiation leucine pulse must have been subsequently adopted with nonradioactive leucine, as well as the pieces have been fixed but instead analyzed besides electron microscopy as well as transmission line during some different points in time.Effects from either the radioactive elements with leucine throughout the reflective coating surrounding the tissue fragments formed autoradiographic particles.Such granules eventually passed forward towards the Golgi throughout corresponding different points in time, as well as subsequently towards the cell membranes, whereby they seemed equipped for induction as established zymogen granulates.If a cusp is lost during preparation, which matrix band would provide the best support while restoring
Answer:
I would use a specialized or preformed matrix for the posterior sector.
Explanation:
Losing a cusp is a much more critical situation, that is, there will be less tooth remnant and less resistance to functional and parafunctional forces.
The matrices that are usually used in the posterior sector are matrices that must be burnished and already come with a format to better restore the functional unit of the occlusal surface.
It is important to clarify that cusps are only in the posterior sector and not in the anterior sector.
The cusps, even if they have the most correct selection of the matrix, will fail in their restoration if they are not performed according to the patient's occlusion, under a good dental integration system such as adhesion through resins, and respecting the normal antomy of the piece to be restored.

ASAP Why is ATP used as an active energy source over glucose? A. It is more abundant in food sources. B. It releases its energy quickly in a single reaction. C. It releases its energy slowly through multiple reactions, allowing it to last longer. D. It has more energy.
Answer:
B.
Explanation:
Glucose is an organic molecule that stores ATP or energy while Adenosine triphosphate (ATP) is an energy-carrying molecule.
ATP used as an active energy source over glucose because ATP is a shorter process and releases energy in a single reaction as glucose first converted into ATP and then used as energy in cellular respiration.
Hence, the correct option is "B".

Given the gene sequence GGACCGTCGATCTTC, which of the following choices would represent an inversion mutation? A. GGACTCGATCTTC B. CCACCGTCGATCTTC C. GGACCGTCGATCTTC D. GGACCGTCGATCCTT
Answer:
D. GGACCGTCGATCCTT
Explanation:
Mutation refers to any change in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. According to the question, an INVERSION mutation is a type of mutation in which a segment of a gene gets broken off and reattached in another way on the same DNA. Hence, the only change in inversion mutation is the arrangement of the nucleotide bases on the gene.
Considering the nucleotide sequence: GGACCGTCGATCTTC, the sequence that describes an occurrence of inversion mutation is: GGACCGTCGATCCTT because the segment TTC in the original sequence has been rearranged as CTT in the mutated sequence.
Answer: GGACCGTCGATCCTT
Explanation: mutation means change and there is change in the gene sequence

Which organelle is labeled I? cell membrane ribosome endoplasmic reticulum nucleus
Answer:
"nucleus" seems to be the correct answer.
Explanation:
The nucleus seems to be a significant case wrapped through a double membrane that distinguishes these from the cytoplasm, the nuclear shell. The membranes combine throughout a few areas, allowing the interchange of substances between some of the cytoplasm as well as the nucleus, steps given designated "nuclear pores".The nuclear shell is consistent with either the concentrated endoplasmic reticulum, thereby bonding with either the nucleus.Answer:

You perform a test cross of the dihybrid AaBb and score the phenotypes of 1000 progeny. Assuming independent assortment, how many of the progeny do you expect to display the dominant phenotype for both the A and B genes?
Answer:
4
Explanation:
The number of progeny expected to display the dominant phenotype for both the A and B genes should be 4.
A test cross usually involves crossing an individual whose zygosity is in doubt with an individual that is recessive for both alleles so as to ascertain the zygosity of the former. Hence, for a test cross involving AaBb:
AaBb x aabb
Progeny:
4 AaBb
4 Aabb
4 aaBb
4 aabb
Therefore, the number of progeny expected to display the dominant phenotype for both the A and B genes is 4.

In the DNA isolation process, cells are mixed with sodium chloride (i.e. NaCl) because the sodium (Na ) neutralizes the negative charge of DNA.
a. True
b. False
Answer:
this is true it neutralise easily
It is true that in the DNA isolation process, cells are mixed with sodium chloride (i.e. NaCl) because the sodium (Na ) neutralizes the negative charge of DNA.
What is DNA isolation?DNA extraction is a method of separating DNA from cell membranes, proteins, and other cellular components using physical and/or chemical methods from a sample. In 1869, Friedrich Miescher isolated DNA for the first time.
The ability to extract DNA is critical for studying the genetic causes of disease and developing diagnostics and drugs.
It is also required for forensic science, genome sequencing, detecting bacteria and viruses in the environment, and determining paternity.
Because sodium (Na+) neutralizes the negative charge of DNA, cells are mixed with sodium chloride (i.e. NaCl) during the DNA isolation process. It makes homogenization easier.
Thus, the given statement is true.

The essence of meiosis is that a. specialized cell division reduces the chromosome number by half b. gametes are formed that are diploid c. specialized cell division doubles the chromosome number d. gametes are formed that are haploid e. a and d are correct
Answer:
e. a and d are correct
Explanation:
Meiosis produces 4 daughter cells that are haploid. Haploid means they have half of the chromosomes of the parent cell.
The essence of meiosis is that specialized cell division reduces the chromosome number by half and gametes are formed that are haploid.
Therefore option e is the right answer.
What is meiosis?A single cell splits twice during the meiotic process, resulting in four cells with half the original genetic material. These cells are our sex cells—eggs in females and sperm in males—and they are produced by a specific form of germ cell division in sexually reproducing species. Two rounds of division are necessary, and the end product is four cells with just one copy of each chromosome. The goal is to produce gametes, or sperm and eggs, that contain half of the parent cells' genetic makeup. Meiosis is characterized by DNA replication, two rounds of cell division, and the production of four daughter cells, each of which has half as many chromosomes as the parent cell.To learn more about meiosis, refer

n your lab you are studying the genome of venomous rattlesnakes to find the gene which codes for their venom glands. You have two rattlesnakes, one rattlesnake has a mutation but can still produce venom. You compare his DNA to a normal rattlesnake. What type of mutation has occurred? Normal: AATCGCTACGCACGTCAG Mutated: TATCGCTACGCACGTCAG
Answer:
There are no options but the kind of mutation that occurred by carefully observing both sequences is:
POINT SUBSTITUTION MUTATION
Explanation:
Mutation is any change, whether small or big, in the nucleotide sequence of a gene (DNA). Mutation occurs from time to time in an organism either by a mistake during DNA replication or induced by a mutagen (mutation-causing substance). Mutation can be of different types depending on the effect on the mutant.
In this case of comparing the DNA sequence two rattle snakes, the sequences of the two snakes are:
Normal: AATCGCTACGCACGTCAG
Mutated: TATCGCTACGCACGTCAG
By carefully observing the two DNA sequences, one would realize that the only difference in the two sequences is the first nucleotide base. That is, in the normal sequence, th first base is Adenine (A) while in the mutated sequence, the first base is Thymine (T).
This type of mutation that involves only one nucleotide base is called POINT MUTATION. It can also be noticed that base "A" was changed "T". Hence, this is a type of SUBSTITUTION MUTATION because a single base was replaced by another in the sequence.

1. How are wavelength, frequency, and energy related to each other?
Answer:
wavelength: the distance between successive crests of a wave
frequency: the rate per second of a vibration constituting a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light)
electromagnetic energy is used for wifi, cell phones, microwave ovens etc.
the electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visisble light, ultraviolet, xrays and gamma rays
the only part we can see is visible light
visible light can be characterised by the colours of the rainbow
the longest wavelength is red and the shortest is violet
when combined, the colour is perceived as white or beige
Answer:
Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy.
Explanation:
WAVELENGTH=

" The role of oxygen in the regulation of respiratory rhythm is quite significant"
Answer:
Pneumotaxic centre in the pons region of the brain can moderate functions of the respiratory rhythm centre. Neural signals from this centre can reduce the duration of inspiration and thereby alter the respiratory rate. A chemosensltive area is situated adjacent to the rhythm centre to make necessary adjustments in the respiratory process. Receptors associated with aortic arch and carotid artery also can recognise changes in CO
