Polymerase activity ability to nick intact is - 5' to 3' Exonuclease.

<h3>What is DNA Polymerase 1 ?</h3>

An enzyme called DNA polymerase I takes role in the replication of bacterial DNA. It was the first known DNA polymerase, and Arthur Kornberg discovered it in 1956. It was first identified in E. coli and is found in all prokaryotes.

Activities ; In addition to having a 3'–5' exonuclease activity, or "proofreading" function, DNA Polymerase I also has a 5'–3' exonuclease activity, which allows the enzyme to replace nucleotides in the expanding strand of DNA via nick translation.

Importance ; By eliminating RNA primers and substituting ribonucleotides with DNA, Pol I helps join Okazaki fragments as part of its physiological role in supporting the repair of damaged DNA.

the diagram below represents levels of glucose and insulin found within the bloodstream of a healthy person

Makovka662 [10]

The increase in insulin level following an increase in glucose level in the blood can best be explained by A FEED BACK MECHANISM THAT REGULATE THE BLOOD GLUCOSE LEVEL.
Insulin is an hormone that is secreted by the pancreas and it functions by regulating the amount of glucose that is found in the blood. When the level of glucose in the blood is higher than normal, insulin interfere by converting the excess glucose into glycogen. The glycogen is stored in the liver and in the skeletal muscles and they will only be converted back into glucose, if the level of glucose in the blood is lower than normal.
