Question

The sequences of satellite DNA fall into different types, each with a different repeat unit of length _____

(a) 5–400 Mbp

(b) 3–300 kbp

(c) 6–900 Mbp

(d) 5–200 bp

I had been asked this question in examination.

Asked question is from Genome Anatomy in chapter Collecting & Storing Sequences in Laboratory of Bioinformatics

Answer 1

Right choice is (d) 5–200 bp

To explain I would say: Because of the skewed base composition of regions that have repeats, they may be purified by virtue of having different buoyant densities. The repeat unit of length is 5–200 bp and not in the scale if Mega.
