If a DNA molecule has 24% adenine, what is the percentage of guanine in the same DNA molecule?
artcher [175]

Answer:

26%

Explanation:

Adenine pairs with thymine.

Guanine pairs with cytosine.

If 24% of the DNA molecule is adenine, that means that there is 24% thymine. This is because they pair together so they have to be equal. That is 48% of the DNA molecule. To find the percentage of guanine, we need to minus 48% from the total 100%.

100 - 48 = 52

Then divide by 2 because you have guanine AND cytosine.

52/2 = 26

Therefore, your final answer is 26% of guanine is in the DNA molecule.

<h3><u>Answer;</u></h3>

Independent Segregation

<h3><u>Explanation</u>;</h3>
  • <em><u>According to Mendel's law of segregation, a sperm or egg carries only one allele for each inherited trait because allele pairs separate from each other during the production of gametes. Independent segregation occurs as a result of separation of homologous chromosomes during anaphase I of meiosis I.</u></em>
  • The law of independent assortment on the other hand, states that each pair of alleles separate independently of the other pairs of alleles during gamete formation. Independent assortment results from the orientation of homologous chromosomes in metaphase I of meiosis I.

Which physiologic process allows hormones to exert influence upon some cells and not others?
nignag [31]

Answer:

receptor binding

Explanation:

Hormones are able to act specifically on target cells through receptor binding. This process enables target cells to react to a specific hormone only. The cells have hormone receptors within or on their surface which permits the specific hormone to act on it, thereby initiating a series of functions of the particular cell that has the hormone receptor. For example, thyroid receptors respond to thyroid-stimulating hormone.
