How does a deletion mutation differ from a substitution mutation?

Answer 1

Deletion mutation is deletion of a base from the genetic sequence, which changes the codon reading frame beyond the point of mutation.
Substitution mutation involves replacement of a base (e.g. one purine) by another base (either purine or pyrimidine).

Deletion mutation will lead to frameshift : Substitution mutation will not.

A deletion mutation involves the removal of one or more nucleotides from a DNA sequence, leading to a shift in the reading frame and potentially altering multiple amino acids. A substitution mutation, on the other hand, replaces one nucleotide with another, potentially changing a single amino acid in the resulting protein.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
