23- Given that there are three bases.
If there are two bases in one codon then the number of codons will be 3*3 = 9
If there are three bases in one codon then the number of codons will be 3*3*3 = 27
If there are four bases in one codon then the number of codons will be 3*3*3*3 = 81
If there are five bases in one codon then the number of codons will be 3*3*3*3*3 = 343
Given that only 26 amino acids are needed for the Arth organism. So minimum codon could be 26 + 1 (Stop codon)
So the answer is three bases per codon.
Option B is the correct answer.
24 - 
As shown in the figure open reading Start codon and ends before stop codon, So in the given sequence open reading frame starts from 57th base and ends at 65th base.
So answer is option B - 57-65.
25- Protein coding sequence is AUG GUC ACA. It encodes for N-terminal MET VAL THR- C-terminal.
So correct answer is option D - N-Met Val Thr -C

Task B: Translation
While
a nucleotide is the basic unit of information, three nucleotides,
or codon, is the basic unit of storage. The reason
for this is that each gene codes for a protein, and all proteins
are made from 20 amino acids. Recall that there are 4 different
bases that make up dna. Thus, three bases can encode for 4x4x4 = 64
different symbols. Two base pairs can only encode for 4x4 = 16
symbols, which is...
