Analysis of the genome sequence of an organism shows that an area of the genome contains stretch of several thousand base pairs that differ significantly in % G + C content from the rest of the genome.Most likely this DNA was originally obtained from another organism.

Question

Quizplus · Accepted Answer

A significant difference in G + C content suggests that this stretch of DNA was likely acquired through horizontal gene transfer from another organism with a different G + C content.
