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.

How do scientists construct recombinant DNA molecules?
Masja [62]

Answer:

by combining the DNA of two different organisms

Explanation:

Recombinant DNA is when researchers edit a gene to contain a novel sequence, such as one from another organism

A good example of this in the lab is when scientists combine genes with a fluorescent gene called green fluorescent protein, GFP. This is from jellyfish. The gene sequence can be tracked on to the end of a gene of interest in a cell population or organism. When the gene is transcribed and translated, the GFP sequence will also be transcribed and translated. This means it will be fluorescent green and easy to track and visualise in cells.

How can food handlers reduce bacteria to safe levels when preparing vegetables
QveST [7]

These can be done by <u>washing</u> of the vegetables, good kitchen <u>Hygiene</u> and<u> proper storage.</u>

Vegetables are perishables, with some quantity of stored water  and therefore they harbor bacteria.

  • Hands should be washed before handling to prevent contamination.
  • Thorough washing should be done under  running water to remove the bacteria. The water current sweeps away the bacteria.
  • Further washing of the vegetables in the warm water with 2% saline solution is needed to  kill some other bacteria and pesticides  resistant to cold water. This is also remove  pesticides residue  on the leave surfaces.
  • The vegetables should be stored in the refrigerator to slow down the activity of the  bacteria  prior to cooking  or before eating.
