Question

5' - ACTACGTGA - 3' is a replicated sequence of DNA What mutation would produce: 5'ACTTACGTGA 3'? What mutation would produce: 5' ACTACGTGT 3'?

Answer 1

The change going from 5' - ACTACGTGA - 3' to 5'ACTTACGTGA 3' is a point mutation changing 'C' to 'T'. The change going from 5' - ACTACGTGA - 3' to 5'ACTACGTGT 3' is a frameshift mutation removing 'A'.

Step-by-step explanation:

The question you asked pertains to changes in the replication of a DNA sequence. In the case of the mutation from 5' - ACTACGTGA - 3' to 5'ACTTACGTGA 3', this represents a

point mutation

, where one nucleotide base is swapped for another, in this case 'C' was replaced by 'T'. In the mutation from 5' - ACTACGTGA - 3' to 5'ACTACGTGT 3', a

frameshift mutation

has occurred because an 'A' is removed, causing the rest of the sequence to be read differently.

Point mutations

often result in the creation of a different amino acid, which may influence protein functionality.

Frameshift mutations

are generally more deleterious because they can significantly alter the genetic code and potentially lead to the production of an entirely different, non-functioning protein.
