a base sequence of the dna from a gene is shown. atc ggc ta due to a mutation, the base sequence was changed as shown. att ggc ta which type of mutation has occurred in the gene? a deletion b substitution c insertion d translocation

Answer

Brief Explanations:

In the original DNA sequence ATC GGC TA, the second - base 'T' in the first triplet is replaced by 'T' in the mutated sequence ATT GGC TA. Substitution mutation is when one base is replaced by another. Deletion is the removal of a base, insertion is the addition of a base, and translocation involves the movement of a segment of DNA to a non - homologous chromosome.

Answer:

B. Substitution
