LINE,SINE,and Retroviral DNA Sequences are Sometimes Termed

Question

LINE,SINE,and retroviral DNA sequences are sometimes termed
A) "selfish" DNA.
B) selectively neutral.
C) middle repetitive-DNA sequences.
D) unique-sequence DNA.
E) "useless" DNA.

Accepted Answer

LINE, SINE, and retroviral DNA sequences are often referred to as "selfish" DNA because they have no known function in the host genome and exist solely to replicate themselves. They can also occasionally cause mutations or chromosomal rearrangements in the process of their replication, further emphasizing their "selfish" nature.
