23.proliferating cell nuclear antigen acts as vice to secure DNA polymerase attached to DNA template. It floating over the DNA because it's diameter is 35 angstrom.
25. The correct option is- amino acyl tRNA synthetase which attached the tRNA with amino acid with the help of ATP.
26. The correct option is- DNA replication is semiconservative and elongates in the 5' -3' direction.
27. The not correct option is- mRNA seeks out and destroys double stranded RNA from viruses.
