DNA replication is 1conservative 2 dispersive 3 semiconserva

DNA replication is 1)conservative. 2) dispersive. 3) semiconservative. 4) irregular. 5) none of these Which of the following proteins is observed exclusively in association with prokaryotic DNA replication? 1)DNA polymerase I 2) primase 3) helicase 4) single-strand binding proteins 5) telomerase In order to be active, a Cdc-cyclin needs to be 1) singly phosphorylated. 2) acetylated. 3) doubly phosphorylated. 4) doubly methylated. 5) cleaved by proteases.

Solution

DNA replication is semi-conservative. This is because each helix that is created contains one strand from the helix from which it was copied.

DNA polymerase I is the protein associated excusively with DNA replication in prokaryotes

Cdc-cyclin needs to be singly phosphorylated in order to be active
