Concept explainers
(a)
Interpretation:
The amino acid is selected by mRNA codon GAA has to be predicted.
Concept introduction: DNA sequence is always synthesized in
The nucelotide triplet that encodes an amino acids is called codon. Each group of three nucleotides encodes one amino acid. There are 20 amino acid present which are encoded by differnet codon. DNA sequence is always synthesized in
(b)
Interpretation:
The sequence in the original DNA that led to the codon being present in the mRNA has to be predicted.

Interpretation:
If mutation occurs in DNA in which G is substituted for the

- Suppose that 28% of the nucleotides in a DNA molecule are deoxythymidine 5'-monophosphate, and that during DNA replication the percentage amounts of available nucleotide bases art 22% A, 22% C, 28% G. and 28% T. Which base would be depleted first in the replication process?arrow_forwardIf a codon consists of two nucleotides, how many codons would be possible? Would this be a workable code for the purpose of protein synthesis?arrow_forwardThe -chain of hemoglobin is a protein that contains 146 amino acids residues. What minimum number of nucleotides must be present in a strand of mRNA that is coded for this protein?arrow_forward
