Answer:
<em><u>The correct option is A) carbohydrate chain</u></em>
Explanation:
The carbohydrate chain present in the cell membrane helps determine the characteristics of the cell and it also helps to identify the chemical signals from outside the cell. Hence, option A is correct.
Other options, like option B, is not correct because the function of the cholesterol in the cell membrane is to prevent the fatty acids from sticking together. Option D is not correct because transport proteins help some molecules to move inside the cell.
No this virus does not follow the Central Dogma of Biology. The Central Dogma refers to the process involved in cellular replication starting from the replication of DNA, followed by transcription of DNA to RNA, and finally translation of RNA to proteins.
Viruses are special because they hijack cells and use the cell's own mechanisms in order for it replicate. Retroviruses are even more special because they go against the unidirectional flow of the Central Dogma. This is done with the use of their <em>reverse transcriptase.</em>
