1. If the original DNA sequence is AGA CTG, what would the following mutations be?

Question

ACA CTG-----
AGA ACT G-----
AAC TG----
Substation
Deletion
Insertion

Answer 1

1. If the original DNA sequence is AGA CTG, the following mutations would be:

a) ACA CTG
- This is a substitution mutation, where the nucleotide "G" is replaced by "C".

b) AGA ACT G
- This is an insertion mutation, where an additional nucleotide "T" is inserted after the second "A".

c) AAC TG
- This is a deletion mutation, where the nucleotide "G" is deleted.

In summary:
- ACA CTG is a substitution mutation.
- AGA ACT G is an insertion mutation.
- AAC TG is a deletion mutation.
