B) It recognizes thymine dimers in DNA,which make the DNA single-stranded,and serves as a signal for the activation of repair proteins.
C) It stabilizes many forms of RNA which are single-stranded.
D) During replication it binds to single-stranded regions of the lagging strand and prevents it from folding back on itself into double-helical regions.
