What is the first step in the process of DNA replication?

1. DNA ligase is an enzyme that catalyzes the formation of a phosphodiester bond between two DNA strands joining them together. DNA ligase is present in eukaryotes and prokaryotes and...

Since DNA polymerase requires a free 3' OH group for initiation of synthesis, it can synthesize in only one direction by extending the 3' end of the preexisting nucleotide chain....

E. coli, as most microscopic organisms (bacteria), has a single origin of replication on its chromosome. As the DNA opens, two Y-molded designs called replication forks are framed, together making...

1. The bacterial chromosome has commonly one origin of replication. However, the replication occurs in both directions from the origin. As a result, there are two forks of replication in...

DNA strands may act as templates only during specialphase of cell cycle called S-phase, so cell should be in that phase of growth. To perform replication itself, a huge number...

The initiation of the replication process is done by the primase. The primase synthesizes RNA primer for DNA polymerase III, so it can begin the replication process. The right answer...

Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new...

Main-band DNA is the DNA sequences, which do not contain the satellite DNA or other repeated sequences. It is the empirical name, which was given to bands on electrophoregram, which...

Proofreading is a mechanism by which DNA polymerase corrects replication mistakes. Enzyme recognizes imperfection between newly paired nucleotides, deletes the last nucleotide and adds the correct one. As a result...

There are three main steps to DNA replication: initiation, elongation, and termination. In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which...
