Answer: B. guanine
In a double helical structure of the DNA, the two strands of the DNA lies in a anti-parallel conformation. The complementary strands of the DNA follows the complementary base pairing rule given by Chargaff. It states that any cell of the organism should have 1:1 ratio of the pyrimidine and purine basis. The amount of thymine is equal to adenine and the amount of cytosine is to guanine. Adenine forms double hydrogen bond with Thymine and Cytosine forms triple hydrogen bond Guanine.

Around 5-6 days after the retrieval
<h3><u>Answer</u>;</h3>
D. reproduce and increase the frequency of their genes in the population
<h3><u>Explanation;</u></h3>
- Natural selection refers to the process that occurs naturally by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment.
- <em><u>For example, a prey population consists of individuals with a variety of running speeds, will be better adapted to the environment as they will be able to run away from their predators and hence reproduce and increase the frequency of their genes in the population.</u></em>
Answer:
DNA
Explanation:
DNA is composed of two complementary strands oriented antiparallel to each other with the phosphodiester backbones on the exterior of the molecule. The nitrogenous bases of each strand face each other and complementary bases hydrogen bond to each other, stabilizing the double helix.
