The provided question is incomplete as the options are not given, however on the general knowledge the answer is given:
Answer:
The correct answer is - cytoskeleton, plant cell wall, plasma membrane.
Explanation:
The cytoskeleton is the component that helps in the provided different functions in an organism such as maintaining cell shape, cell signaling by filament systems regulation, and facilitate movement and support.
The plant cell wall also helps in providing the cell to maintain its shape and offers the structural support and cell to cell communication is done by the plasmodesmata that also helps in the movement of the small molecules to transfer from one to another.
The plasma membrane has specific receptors present on them that help in the cell signaling, plasma membrane is semi-permeable and so are able to transport the molecules selectively or with the help of transport protein.
Thus, the correct answer is - cytoskeleton, plant cell wall, plasma membrane.
Answer:
By preventing bases from being damaged present in phosphate sugar backbone.
Explanation:
The sugar phosphate backbone is a significant structural component of DNA. It comprises of 5-carbon deoxyribose sugars and phosphate gatherings. DNA is twisted into a right-gave twofold helix. The strands are anti parallel for example one runs 3' to 5', the other run 5' to 3'.
This is finished by the sugar phosphate backbone contorting around itself in a curl or coil. The motivation behind this twisting or coiling is to ensure safety of the nitrogenous bases inside backbone, and keep them from being damaged. DNA is entirely stable because of rungs of hydrophobic "ladder" and adversely charged phosphate sugar backbone of DNA. These highlights cause DNA to can repulse water and would not hydrolyzed.
