There are special proteins that help to open up DNA double helix in front of the replication fork. These proteins are
1 DNA ligase
2 DNA topoisomerase I
3 DNA gyrase
4 DNA polymerase I
Explanation:
DNA gyrase is an essential bacterial enzyme that catalyzes the ATP-dependent negative supercoiling of double-stranded closed-circular DNA. The gyrase makes either single or double stranded cuts' and also catalyzes localized movement that have the effect of 'undoing' the twist \& knots created during supercoiling.

RNA does not possess
1 uracil
2 thymine
3 adenine
4 cytosine.
Explanation:
RNA does not possess of thymine.

There are special proteins that help to open up DNA double helix in front of the replication fork. These proteins are
1 DNA ligase
2 DNA topoisomerase I
3 DNA gyrase
4 DNA polymerase I
Explanation:
DNA gyrase is an essential bacterial enzyme that catalyzes the ATP-dependent negative supercoiling of double-stranded closed-circular DNA proteins are required for DNA replication at a replication fork.

Activation of an amino acid during protein synthesis requires a participation of specific molecule of :
1 m-RNA
2 t-RNA
3 r-RNA
4 None of these
Explanation:
Activation of an amino acid during protein synthesis requires a participation of specific molecule of \(\mathrm{t}\)-RNA.
