The reason it is called a Frameshift mutation is because it alters the "reading frame" of the bases. The bases are normally read as A. codons, in groups of 3

B. nitrogen bases, in groups of 2

C. anti-codons, in groups of 4

A. codons, in groups of 3

Explanation:

The three-letter nature of codons means that the four nucleotides found in mRNA — A, U, G, and C — can produce a total of 64 different combinations. Of these 64 codons, 61 represent amino acids, and the remaining three represent stop signals, which trigger the end of protein synthesis.

Explanation:

The reason it is called a Frameshift mutation is because it alters the "reading frame" of the bases. The bases are normally read as codons, in groups of 3.

gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes.
