Dna contain thymine which is one of the 4 bases.
Answer:
A buffer is simply a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. Buffers work by reacting with any added acid or base to control the pH.
Explanation:
Answer:
The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.
Speciation start to take place on a genetic level between two isolated populations by Allele frequencies change in different ways.
<h3><u>
Explanation:</u></h3>
The field of study called the population genetics helps us to understand about the composition of a selected population and the frequencies of alleles and how they get changed over a specific period of time. The mechanism called the adaptation mechanism ,mutation and gene flow determines the allele frequency changes in natural population.
Micro evolution refers to the changes in gene pool from one generation to another. Natural selection, mutation, genetic drift and gene flow are considered as the four forces of this evolution. When the allele frequencies starts to get changed in different ways, the Speciation starts to take place.
