Question

Recombination signal sequences (RSSs) ______________________________. (Select all that apply.)

Group of answer choices

A.contain spacer sequences that are either 7 or 9 base pairs in length

B. are located between the exons encoding the leader peptide and the V-region segments

C. contain conserved DNA sequences that are recognized by enzymes that facilitate the cutting and rejoining of gene segments

D. ensure that the gene segments undergoing somatic recombination are joined in the correct order

Answer 1

C. contain conserved DNA sequences that are recognized by enzymes that facilitate the cutting and rejoining of gene segments.

Recombination signal sequences guide the enzyme complex during V(D)J recombination in immature B cells and T cells.
