Which type of mutation does the change in this nucleotide sequence represent? gcttagcgc → gcttatagcgc a. duplication b. inversion c. substitution d. translocation

the correct answer for plato is duplication

The correct answer is -

A.duplication.

Duplication can be described as a type of mutation that occurs when a portion of DNA sequence or a chromosome is duplicated, resulting in mutiple copy of that region. Duplication can result from misaligned homologous chromosomes, which undergo unequal crossing-over during meiosis.

In the given sequence-

GCTTAGCGC → GCTTATAGCGC

TA nucleotide sequence in the original DNA is duplicated, resulting in another TA sequence in the mutated DNA.

Thus, option A) is the right answer.
