write a 2 - 3 sentence summarizing the process of DNA replication

Expert Solution

The process of copying / replicating chromosome DNA accurately for its transmission from generation to generation is known as Replication. A new complimentary strand is synthesized opposite to parental template strands producing two identical DNA helixes.

There are 3 basic steps of this process-

1)Initiation 2) elongation 3) termination

1)Initiation - DNA replication begins at Ori sequence, helicase enzyme opens up the parental helix and primer is laid by the enzyme Primase.

2) Elongation - DNA polymerase elongates the primers by nucleophillic attack of 3'OH group on inner phosphorous atom of incoming dNTPsand forms leading and lagging strands against templates.

3) termination - the proceee of replication ends after copying the entire chromosome of the organism. In prokaryotes ter-tus complex inhibits the replication fork and stops it while in eukaryotes Telomerase catalyse the replication at ends / Telomeres and stops the process.

DNA replication is a [1] process because each new molecule has [2] strand of [3] DNA and [4] of [5] DNA. The role of [6] is to unzip the double helix. DNA polymerase extends the [7] primers made by the primase. On the [8] strand the DNA synthesis is discontinuous, on the [9] strand is instead continuous. The reason for this difference is that [10]. Please fill in the numbered blanks and for the [10] can you make a sentence...

DNA replication requires many enzymes to accomplish the process successfully. This results in a replication process that is known to be bi-directional, semi-conservative and semi-discontinuous. You discover a new prokaryotic organism that lacks the gene coding for an DNA polymerase I enzyme, and therefore this enzyme is not made in this species. Additionally, the DNA polymerase III enzyme from this organism lacks any 3’ to 5’ nuclease activity but has 5’ to 3’ nuclease activity. Based on what you know...
