Concept explainers
(a)
Interpretation:
The dipeptide molecule formed from the given DNA base sequence should be given.
Concept Introduction:
Genetic information is included in DNA and most of them code for a particular protein. Consecutive three base pairs represent a single amino acid. Genetic information coded in DNA, first transcribed in to mRNA sequence and using that mRNA molecule translate into an amino acid sequence which can be defined as a protein depending on the number of amino acids.
(b)
Interpretation:
The dipeptide sequence difference should be given when the point mutation is happen in the DNA sequence.
Concept Introduction:
Point mutations are DNA molecular level changes in the sequence. This includes insertions, deletions and substitutions. In given question, it only includes substitutions. Substitution point mutations whre the base pair sequence changes which means one base replace with the other base. This may cause to change the amino acid sequence of the peptide. But, there will be some occasions where the amino acid sequence does not change.
