What sequence of bases would pair with the DNA sequence TGAACTACCGAT?

Answers

Answer:

ACTTGATGGCTA

Explanation:

Keep this in mind:

Adenine → Thymine (A → T)

Thymine → Adenine (T → A)

Cytosine → Guanine (C → G)

Guanine → Cytosine (G → C)

Does this make sense? All you're doing is switching the letters out and replacing them with the corresponding one.

The DNA sequence is:

Adenine → Thymine (A → T)Thymine → Adenine (T → A)Cytosine → Guanine (C → G)Guanine → Cytosine (G → C)

What is the DNA sequence in order?

The sequence of the bases (regularly mentioned through the primary letters in their chemical names: A, T, C, and G) encodes the biological information that cells use to broaden and operate. Organizing the collection of DNA is prime for information on the feature of genes and different components of the genome.

Because there are four naturally going on nitrogenous bases, there are 4 one of a kind sorts of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).

What kind of cell is produced by fertilization? Haploid cells or diploid cells

Answers

Haploid cells is the correct awnser

Diploid cell is Produced by fertilization.

What is Fertilization?

Fertilisation or fertilization (see spelling differences), also known as generative fertilisation, syngamy and impregnation, is the fusion of gametes to give rise to a new individual organism or offspring and initiate its development.

Processes such as insemination or pollination which happen before the fusion of gametes are also sometimes informally called fertilisation.

During double fertilisation in angiosperms the haploid male gamete combines with two haploid polar nuclei to form a triploid primary endosperm nucleus by the process of vegetative fertilisation.

Therefore, Diploid cell is Produced by fertilization.

Explanation:

What accounts for the differences in the properties of the various polysaccharides?​

Answers

Answer:

Polysaccharides are present in all living organisms where they carry out one or more of their diverse functions. While there is no specific category or definition of a complex polysaccharide, most are structurally complex. Polysaccharides contain 1–5 different monosaccharide (sugar) units. The different sugar units may have different anomeric configurations and/or be joined by different glycosidic linkages. Polysaccharides may be linear or branched. Branches may be short saccharide units on a linear backbone or the molecule may have a branch-on-branch structure; in either case, the branches may be isolated or clustered. Polysaccharides may contain non‐carbohydrate groups. Esters or cyclic acetal groups, when present, can be removed by appropriate treatments. All polysaccharides are polydisperse, i. e., are present in a range of molecular weights rather than having a single molecular weight

- ¿Qué ruta sigue cada uno DE LOS TRIGLICERIDOS en su afán de obtener energía?… ¡sí, energía llamada ATP! - Ruta metabólica que siguieron el glicerol y el ácido graso.

Answers

Answer:

Los trigliceridos antes de ser disociados en moleculas energeticas necesitan ser absorvidos.

Para eso es importante aclarar que se absorbe nen elintestino en forma de quilomicron, por su caracteristica hidrofuga y son emulsionados por el jugo pancreatico y los jugos provenientes de la vesicula.

Una vez absorbido, este puede seguir diferentes rutas metabolicas de un cuerdo a la necesidad energetica de la persona.

Explanation:

Las grasas contienen una gran aporte de ATP posterior a la adicion de CO2 y H20, en los procesos de beta oxidacion y el ciclo del acido citrico.

El metabolismo de estos se considera toxico en momentos prolongados ya que el  producto de su metabolizacion son los cuerpos cetonicos. Los cuerpos cetonicos aumentan la cetoacidosis de la sangre y atraviezan la barrera hematoencefalica.

Which is one of the ecosystems found in intertidal zones?

Explanation:

Determine the statement that is logically equivalent to this conditional statement. If there is a thunderstorm, the lake floods.

Answers

Answer:

This question lacks options, the options are:

A) If the lake does not flood, there is a thunderstorm.

B) If the lake floods, then there is not a thunderstorm.

C) If there is not a thunderstorm, the lake does not flood.

D) If the lake does not flood, then there is not a thunderstorm.

The correct answer is D

Explanation:

A conditional statement is a statement whose effect is dependent on another, it is usually recognized with the IF word. A Contrapositive of an original conditional statement, is the inverse of the converse of an original statement that doesn't change the meaning of the original statement.

For example; A -> B is the original conditional statement

Converse is B -> A

The Contrapositive is (not B -> not A)

The original conditional statement is: If there is a thunderstorm, the lake floods.

(This means that there is flooding of the lake in the presence of a thunderstorm)

The contrapositive of this statement is:

If the lake does not flood, then there is not a thunderstorm.

(This retains the meaning of the original statement. It means that the absence of a flood certainly means the absence of a thunderstorm)

Since the contrapositive is logically equivalent to the conditional statement, then the option D is the logically equivalent to the conditional statement.

Note: Option C is wrong because other factors might cause flooding of the lake, so the absence of thunderstorm doesn't mean there'll be no flooding of the lake but no flooding certainly means no thunderstorm, which option D is portraying.

The ______ head binds and ______ splits ATP to ADP and inorganic phosphate. The final outcome is _______.

Answers

Answer:

The process of excitation-contraction coupling begins with the depolarization and subsequent excitation of a motor nerve. Afterwards, acetylcholine is released from the motor endplate and the muscle sarcolemma membrane depolarizes. Calcium is released and binds to troponin resulting in the exposure of actin binding sites. The myosin head binds and Myosin ATPase splits ATP to ADP and inorganic phosphate. The final outcome is muscle shortening.

Explanation:

The paragraph above summarizes the process of muscle contraction, which happens thanks to the release of acetylcholine in the neuromuscular junction, after the neuron is depolarized. The presence of acetylcholine will ultimately lead to the release of stored calcium so it can bind to a protein in the sarcomere called troponin. The binding of calcium and troponin will expose actin binding sites, making the binding of actin and myosin possible. The ATPase found in the myosin head will make use of ATP to produce the movement of myosin - this is how muscle contraction happens.

Lung cancer cells do not respond to the signals that regulate the growth of normal lung cells. Which of the following processes is NOT appropriately regulated in the cancerous cells?

Answers

Answer:

The correct answer is : mitosis.

Explanation:

Malignant growth or cancer is basically an abnormality of mitosis - the ordinary 'checkpoints' directing mitosis are ignored by the tumor cell. Disease starts when a single cell is altered, or changed over from an ordinary cell to a malignant growth cell.  

Mitosis is firmly constrained by the qualities inside each cell. If genes did not control or perform their work properly  occurs in only a single cell, it can reproduce itself to make new cells that are likewise uncontrollable and leads to tumor or cancer.
