For Dispersed Moderately Repetitive DNA in the Human Genome,which of the Following

Question

For dispersed moderately repetitive DNA in the human genome,which of the following is incorrect?
A) LINEs are the longest and L1 is the only functional element in the genome
B) SINEs are typically 100-400 bp in length and the most abundant
C) Transposable elements with LTRs are rarely observed
D) DNA transposons comprise about 3% of the genome
E) None of these

Accepted Answer

Transposable elements with LTRs (long terminal repeats) are actually quite common in the human genome, comprising about 8% of the genome. The other statements are generally correct: LINEs (long interspersed elements) are the longest and L1 is a functional element, SINEs (short interspersed elements) are the most abundant, and DNA transposons make up about 3% of the genome.
