a mutation in the dna changes an adenine to a guanine. this adenine was the a in the aug of a start codon for a gene. what process or processes would this mutation impact?

Answers

Answer 1

Mutations must occur in cells that produce the next generation and affect the hereditary material in order to affect an organism's descendants.

Mutations can have an effect on an organism by altering its physical characteristics (or phenotype) or by altering the way DNA codes genetic information (genotype). When mutations occur, they can either terminate (kill) an organism or be partially lethal. Mutations can occur as a result of errors in DNA replication during cell division, mutagen exposure, or viral infection. Germline mutation(those that occur in eggs and sperm) can be passed down to offspring, whereas somatic mutations (those that occur in body cells) cannot.

a man is heterozygous for the hemoglobin gene, with one normal allele and one sickle allele. what are the chances that one of his sperm cells will have the sickle allele for hemoglobin?

Answers

Any given child has a 50% chance of receiving one copy of the HbS gene, resulting in the sickle cell anemia trait.

Sickle cell anemia cannot be passed down from one parent to the next if only one possesses the trait. Each child has a 25% chance (or 1 in 4) of having sickle cell anemia if both parents have the trait. SCT is a condition that affects people who inherit one normal gene and one sickle cell gene.

The parent genotype cannot have RR alleles for their coat because the smooth coat phenotype is present in the offspring. Similar to this, the rough, black parent is unable to have BB alleles in its genotype because doing so will prevent its offspring from having a white coat color.

why do some plant species that are independent at low altitudes become interdependent at high altitudes

Answers

Although these advantages are not as important at low altitudes, the plants' benefits to one another enable them survive at high altitudes.

The extreme conditions of their environment, which include low temperatures, aridity, UV radiation, and a brief growing season, force high-altitude plants to adapt. High altitudes are inhospitable to tree growth due to the chilly temperatures and scarcity of precipitation. Low air density and atmospheric pressure at high altitude result in lower carbon dioxide levels and a slower transpiration rate, which are both necessary for plants to develop.

Answers

The complementary translated RNA code on the other side would be CUUAGC.

DNA is changed during transcription into m-RNA. The RNA polymerase enzyme is responsible for it. Adenine, thymine, cytosine, and guanine are some of the nitrogenous bases that make up the DNA in a certain order. In m-RNA, guanine is paired with cytosine or vice-versa, adenine is paired with uracil, and thymine is paired with adenine on m-RNA transcript. This is because RNA can't have thymine on its strand. The nitrogenous base sequence on the DNA template determines the nitrogenous base sequence on the m-RNA. If the DNA base sequence is GAATCG, the transcript's base sequence will be CUUAGC.

RNA polymerases, which link nucleotides to create an RNA strand using a DNA strand as a template, carry out transcription. mRNA is therefore translated from DNA which binds amino acids by peptide bonds.

Answers

The body's estimated total number of billions of capillaries is seven, based on the equation of continuity is 7×[tex]10^{9}[/tex].

The blood's density is relatively constant from the aorta to the capillaries. The volume flow rate across all capillaries must be equal to the volume flow rate in the aorta according to the continuity equation.

The area of a sample capillary is multiplied by the overall number of capillaries N to get the total area of all of the capillaries.

Assume that A1 represents the aorta and that A2 represents all of the blood vessels.

Then A1 = N× π×r²

where r = 4 x [tex]10^{4}[/tex] cm is thought to be the capillary's average radius. We can infer from the continuity equation that

v2×A2 = v1×A1

v2×π×N×r²cap = v1×π×r²arota

When we substitute and solve for N in the equation, we obtain the value of N as 7×[tex]10^{9}[/tex].

Explanation:

Answer:

Explanation:

Paddy is a common crop in our country, and I am familiar with it since my early childhood. Rice, which we get from paddy, is the staple food in our country and our food demand is mainly supported by this crop. I would like to thank you for this great topic which expects me to talk about a crop I am familiar with.

Paddy is grown in almost all parts of our country by the farmers. But the north part of the country is particularly suitable to produce the finest quality of paddy due to its arable lands and higher rainfalls. The paddy plant grows well in fertile lands where plenty of water supplies is available. But it can't grow in water.

Rice is the main source for our daily carbohydrate requirements. No doubt, this is the most important crop in our country. If we can't grow plenty of paddy plants, we won't have enough rice. And as a consequence, we won't have enough food supply for our people. This epitomises how important this single crop is for us!  

Every nation has its own main crop and its economy is much influenced by it. In our country, paddy has similar influences on our economy. I like this paddy plant as it looks beautiful in the green field and whenever I visit a rural area, lush paddy fields take my heart away. They are such a beautiful sight to look at. The golden paddy, when they ripe, and the green plants, when they are yet to ripe, look amazing when it dances with the rhythm of the wind, it's heavenly. I also like this crop because it is our main food source.

The importance of this crop is monumental, especially for our country. If we do not have this crop in our country even for a single year, we would have a huge problem fulfilling our daily food needs.

When Lily left her house in the morning, her cell phone battery was partially charged. The charge remaining in Lily's battery, as a percentage, can be modeled by the equation B=-4t+52,B=4t+52, where t is the number of hours since Lily left her house. What is the x-intercept of the equation and what is its interpretation in the context of the problem?
