2. DNA opens readily because of the action of helicase.
DNA can't open itself, but it is done by the action of specialized unwinding enzyme. An enzyme, DNA helicase opens DNA inorder to read the genetic code for replication and transcription. DNA helicase are motor proteins that melts the hydrogen bonds and thereby unpackage an organism's genes. They move directionally along a nucleic acid phosphodiester backbone and separats 2 annealed nucleic acid strands using energy from ATP hydrolysis.
3. The Vibrio cholerae lose water and shrink when placed into a hypertonic solution. Hypertonic solution had higher concentration than that of vibrio cells. So, water content in the cell moves towards external hypertonic solution and thereby cells will shrink.

Bacteria use DNA methylation as a method to label their DNA, so they can identify foreign DNA and degrade it using restriction endonucleases. This DNA methylation is different than that of eukaryotic organisms, in that it adds a methyl group to adenine. This makes the bacterial DNA methylation system a potential antibiotic target. Question 1: (3 marks) Based on what we learned about enzyme activity and regulation, explain what you would expect for the following enzymes: How would this differ...
