Answer:
B. The bacteria can cut the viral DNA at its specific restriction site but protect their own chromosomal DNA by modifying its bases and blocking the restriction enzyme.
Explanation:
There are two main reasons why bacteria cuts the viral DNA sequence but not its own.
1) There are specific restriction sites in the genome sequence of bacteriophage that restriction enzymes identify and target. These restriction sites are not present in the genome sequence of bacteria.
2) Even if sometimes the bacteria has a sequence resembling to bacteriophage and has the restriction site, still bacteria prevents the cleavage of its own chromosomes by methylating the bases of the restriction sites. When restriction site is methylated, bacteria just cannot chop it down that prevents it overall from degradation(please see the figure for better understanding).
Note: <em>Although option A can also somehow fit but option B is the perfect option because of the reason no 2.</em>
Hope it help!
Sorry i only know some of these but here is what i know.
1. the chemical bonds are more attracted to the oxygen molecules because while the oxygen already have enough electrons, the oxygens still want more resulting in a bent shape.
2. polar
3. hydrogen bonds are formed
4.adhesive
5.high
6. water molecules bond from hydrogen bonds, and this causes the water to stick together forming cohesion. the water strider floats because the weight of the insect is less then the strength of the hydrogen bonds.
7. water is the universal solvent because it is a polar substance and most things will dissolve in it. usually fats will not dissolve in water ex. oil will no mix with water
