Q.
Which mutation o f the genetic bases gives the proof
that codon is triplet and reads in a contagious
manner?
Molecular Basis of Inheritance
Solution:
Frameshift mutation of the genetic bases (deletion or
addition) gives the proof that codon is triplet and reads in
contagious manner. Deletion or addition of a base pair
disturb the reading frame of DNA or $mRNA$.
