1. During DNA replication, the single-strand DNA-binding (SSB) proteins … a) are generally found more on the leading strand than the lagging strand. b) bind cooperatively to single-stranded DNA and cover the bases to prevent base-pairing. c) prevent the folding of the single-stranded DNA. d) bind cooperatively to short hairpin helices that readily form in the single-stranded DNA. e) All of the above.

Solution

Answer= e] All of the above

During DNA replication, the single-strand DNA-binding (SSB) proteins …

a) are generally found more on the leading strand than the lagging strand.= because leading strand is replicate in continuous manner

b) bind cooperatively to single-stranded DNA and cover the bases to prevent base-pairing.= It binds cooperatively in sequence independent manner

c) prevent the folding of the single-stranded DNA.=It keep the two strands separate from one another & prevents the prevent folding of ss DNA

d) bind cooperatively to short hairpin helices that readily form in the single-stranded DNA.
