In addition to highly repetitive and unique DNA sequences,a third category of DNA sequences exists.What is it called,and what types of elements are involved in it?
A)multiple gene family DNA; hemoglobin and 5.0S RNA
B)permissive DNA; centromeres and heterochromatin
C)dominant DNA; euchromatin and heterochromatin
D)composite DNA; telomeres and heterochromatin
E)moderately repetitive DNA; SINEs,LINEs,and VNTRs

Question

Quizplus · Accepted Answer

The third category of DNA sequences is moderately repetitive DNA, which involves SINEs (short interspersed nuclear elements), LINEs (long interspersed nuclear elements), and VNTRs (variable number tandem repeats). These are DNA sequences that are present in multiple copies throughout the genome but are not as highly repetitive as the first category. The other answer choices are not correct, as they either do not refer to a third category or involve different types of DNA elements.
