(a) 90–4000 bp long

(b) 80–500 Mbp long

(c) 80–300 bp long

(d) 100–3000 bp long

I got this question in quiz.

The origin of the question is Genome Anatomy topic in chapter Collecting & Storing Sequences in Laboratory of Bioinformatics

Answer 1

Correct option is (c) 80–300 bp long

To elaborate: There exists also (6–8 kbp long) interspersed nuclear elements (LINES). Different types of transposable elements are present in high copy numbers in mammalian genomes in varying manner.
