Answer:
Interphase refers to all stages of the cell cycle other than mitosis. During interphase, cellular organelles double in number, the DNA replicates, and protein synthesis occurs. The chromosomes are not visible and the DNA appears as uncoiled chromatin.
DNA polymerases add nucleotides to the 3′ end of a polynucleotide chain. ... To initiate this reaction, DNA polymerases require a primer with a free 3′-hydroxyl group already base-paired to the template. They cannot start from scratch by adding nucleotides to a free single-stranded DNA template.
How is DNA replicated? Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
Answer:
The population has evolved because there was a change in allele frequencies.
Explanation:
The evolution may be defined as the process of the change of the species characteristics with the passage of the time. The natural selection, mutation and the genetic drift might cause the evolution.
The population might have evolved as the allele frequencies has changed from the generation to the generation. Although the variation among the population is quite less but the variation is still enough for the evolution of the elephant seals.
Thus, the correct answer is option (D).
