Q.Which one of the following feature is absent in a virus

a) Reproduce within host cell
b) Presence of cell wall
c) Fully parasitic in nature
d) Presence of either DNA or RNA

✔Answer

✔Solution

Correct Answer Is : Presence of cell wall

Solution Is : A virus has a simple structure ,it has no internal cellular structure no cell wall or cell membrane, just the protein coat that holds the string of nucleic that holds the string of a nucleic acid. It is made only of a nucleic acid + a protein coat. A cell wall is a layer lOcated outside the cell membrane found in plants, fungi, bacteria, algae and archaea.

Ribosome`s main activity is

Microbial degradation of nitrates into atmospheric nitrogen is known as:

a) Ammonification
b) DE nitrification
c) Putrefaction
d) Nitrification

✔Answer

✔Solution

Correct Answer Is : DE nitrification

Solution Is : Dentrification` is the biological conversion of nitrate to nitrogen gas, nitric oxide or nitrous oxide. These compounds are gaseous compounds and are not readily available for microbial growth; therefore they are typically released to the atmosphere.

c) Polygene
d) Complementary

✔Answer

✔Solution

Correct Answer Is : Pleiotropic

Solution Is : Pleiotropic gene is a gene that causes a number of distinct but seemingly unrelated phenotypic effects.

An enzyme produced by HIV that allows the integration of HIV DNA into the host cell`s DNA is:

a) DNA gyrase
b) Ligase
c) Integrase
d) Helicase

✔Answer

✔Solution

Correct Answer Is : Integrase
