Answer 1

68. Single-strand DNA-binding proteins or Single-strand binding proteins (SSBP) are specialized tetrameric protein. During DNA replication, the newly generated single -stranded DNA by helicases, another kind of proteins bind to this newly exposed single-stranded DNA to stabilize the separated strands and thereby preventing their reassociation and help to hold the DNA strands apart while they are being replicated. These proteins are called Single strand DNA-binding proteins or Single strand binding proteins (SSBP).

Nuclease is an enzyme that breaks the bonds between nucleotides during replication.

Ligase is an enzyme that joins the fragments of the repaired lagging strand.

Primase is an enzyme (specialized RNA polymerase) that synthesize a short RNA primer to initiate the process of DNA replication.

DNA polymerase is the main enzyme of the replication process. It catalyzes the DNA synthesis and repair the gaps in lagging strand.

So, the correct option is option-1 "single-strand DNA-binding proteins".
