<h2>Density dependent </h2>
Explanation:
Density dependent inhibition is the process exhibited by most normal (anchorage dependent) animal cells in culture that stop dividing once a critical cell density is reached
The critical density is considerably higher for most cells than the density at which a mono-layer is formed
As cells become more numerous, the cell surface proteins of one cell contact the adjoining cells and they signal each other to stop dividing
Normal cells proliferate until they reach finite density but cancer cells are not sensitive to density dependent inhibition
Answer:
False
Explanation:
A cell membrane is not rigid a cell wall is rigid.
Answer:
C. Nucleic acid synthesis
Explanation:
AZT, azidothymidine, is an antiviral drug used to check the viral population by blocking the process of reproduction. The azidothymidin is particularly effective against human immunodeficiency virus (HIV) as this drug inhibits the activity of reverse transcriptase which is required for the formation of a DNA copy of the RNA genome of the virus.
Similarly, Valacyclovir is an antiviral drug that inhibits viral reproduction by blocking the DNA polymerases. The Valacyclovir serves as a prodrug of acyclovir.
