A DNA segment has base order AGC TTA TCG. Which copy exhibits a frameshift mutation through deletion? (1 point)
A.) TTA TCG
B.) AGC TCG
C.) AGC TTA TAG
D.) AGC TTT CG
The correct answer is C.) AGC TTA TAG.
In a frameshift mutation through deletion, a nucleotide is deleted from the DNA sequence. In this case, the nucleotide sequence "AGC TTA TCG" has three nucleotides deleted (TTA), resulting in the sequence "AGC TAG". This change causes a shift in the reading frame of the genetic code, potentially resulting in a completely different amino acid sequence during protein synthesis.
