A portion of DNA has the following sequence: ATACCG. What number of codons would this segment code for?
A. 6
B. 3
C. 2***
D. 1
I think it is C...?
To determine the number of codons in a DNA sequence, we need to first understand what a codon is. A codon is a sequence of three nucleotides (A, T, G, or C) that specify a particular amino acid in a protein.
In the given DNA sequence ATACCG, we can group the nucleotides into sets of three to find the codons: ATA, CCG.
So, this segment of DNA codes for two codons: ATA and CCG.
Therefore, the correct answer is C.
