In a genetic assay, randomly generated fragments of yeast DNA were cloned into a bacterial plasmid containing gene ‘X’ essential for yeast viability on minimal media. The recombinant plasmid was […]

Some of the steps in the process of eukaryotic DNA replication mentioned below require hydrolysis of ATP. (A) Phosphodiester bond formation (B) DNA strand separation by helicase (C) Clamp-loader association […]

The high processivity of DNA polymerases during replication is because of their association with proteins called sliding clamps. For loading onto DNA, sliding clamps require sliding clamp-loaders. Which of the […]

65. The following statements are made on DNA replication: A. Replication fork is a branch point in a replication ‘eye’ or ‘bubble’. B. A replication bubble contains two replication forks. […]

Following are certain statements related to eukaryotic DNA replication: The genome of multicellular animals contain many potential origins of replication. During early development, when embryos are undergoing rapid cell divisions, […]

Given below are few statements related to DNA replication                                            […]

Given below are a set of enzymes in Column A and enzyme activities in Column B.Column A Column B (A) DNA (i) Synthesis of topoisomerase I       Okazakifragment (B) DNA                    (ii) […]

Eukaryotic DNA polymerase a has tightly associated primase activity but moderate processivity. DNA polymerase ϵ and Ꟙ are highly processive but lack primase activity. Given below are four statements about […]

Telomerase, a protein RNA complex, has special reverse transcriptase activity that completes replication of telomerase during DNA synthesis. Although it has many properties similar to DNA polymerase, some of them […]

The following statements are made With reference to DNA replication: Camptothecin causes intra- strand and jnter-strand crosslinks in DNA, leading to stalling of replication forks. Prevention of re-initiation of DNA […]
