What nucleotide position is codon 10, position 2 of a sequence equivalent to?

To determine the nucleotide position corresponding to codon 10, position 2, it's essential to understand how codons are structured and how they relate to nucleotide sequences. A codon is a sequence of three nucleotides that correspond to a specific amino acid or serve as a stop signal during protein synthesis.

In this context, codon 10 refers to the tenth triplet of nucleotides within the sequence. Each codon consists of three nucleotides, so to find the starting nucleotide position of codon 10, you can calculate it by multiplying the codon number by three. For codon 10, this would be:

10 (codon number) x 3 (nucleotides per codon) = 30

However, when you're looking for position 2 of codon 10, you need to subtract 1 from this total since the count begins at 1 for the first nucleotide of that codon. This means we take nucleotide positions 29, 30, and 31 to form codon 10, with position 29 being the second nucleotide of the codon. Therefore, codon 10, position 2 indeed corresponds to nucleotide position 29.
