Question

What are the different types of DNA mutations?

Answer 1

There are three types of DNA Mutations: base substitutions, deletions and insertions.
Base Substitutions. Single base substitutions are called point mutations, recall the point mutation Glu -----> Val which causes sickle-cell disease.
Deletions. ...
Insertions.

Answer 2

Step-by-step explanation:

Substitution- When one DNA base is removed out of the nucleotide sequence and another is substituted. e.g AGC where base G is substituted for Base C becomes ACC.

Deletion - Removal of one or more nucleotides

Addition - When you add another base into the DNA sequence,this can result in a frame shift which may change the amino acid that is coded for.

Duplication - One or multiple bases are repeated

Translocation - A piece of DNA breaks off and doesn't reattach to itself or its homologous pair.

Inversion - A sequence of bases is separated and then reattached in the inverse order.
