What type of mutation has occurred? if this dna molecule proceeds to transcription and translation, what is the impact of this mutation on the production of a protein?

D)This is a point mutation, resulting from the substitution of one nitrogen base. If this strand of DNA is used for transcription, it will affect the coding of ONE amino acid, resulting in placing the correct amino acid in the protein, placing the wrong amino acid in the protein, or coding for the protein to stop building.

Point mutation .

Explanation:

A point mutation is a genetic mutation where a single nucleotide base changed. Point mutation has a variety of effects on protein products, inserted or deleted from a sequence of DNA or RNA. There are many types of point mutation

Frameshift, silent, nonsense, and missense.

Frameshift mutation:- an insertion or deletion of one or more bases.

Silent Mutation:- there is no change of amino acids.

Impact of this mutation on the production of a protein:-

Point mutation usually takes place during DNA replication, it changed the one purine or pyrimidine or may change the amino acid, nucleotide code. A single point mutation can change  the whole DNA sequence of the nucleotide.
