In human chromosomes,satellite DNA sequences of about 170 base pairs in length are present in tandem arrays of up to 1 million base pairs.Found mainly in centromere regions,these DNA sequences are called ________.
A) telomeres
B) primers
C) alphoid families
D) euchromatic regions
E) telomere-associated sequences

Question

Quizplus · Accepted Answer

The description matches the characteristics of alphoid DNA, which is found in the centromere region and consists of tandem arrays of 170-base-pair sequences. Telomeres are found at the ends of chromosomes, primers are short pieces of DNA used in DNA synthesis, euchromatic regions are areas of chromosomes that are loosely packed and actively transcribed, and telomere-associated sequences are also found at the ends of chromosomes.
