Question

QUESTION 13 Genetic change in bacteria can be brought about by Transduction. Mutation. Transformation. Conjugation. All of the above. ooo

Answer 1

13. All the a bove.

Bacteria can under go mutation and bring genetic changes in them. They also can take up DNA from surroundings (transformation ) and bring genetic changes. Viruses can add genes and also conjugation also can bring genetic changes.

14. Degrades glucose in to CO2 and H2O.

Glycolysis produces Pyruvate , NADH, occurs in anaerobic respiration and also does not require O2.

15.Viruses use their own catabolic enzymes.

Viruses are surrounded by protein coat and have either RNA or DNA as the genetic material but never both. Viruses use the host cell machinery to make their own compounds. They have enzymes only to convert DNA in to RNA etc

16. Viruses are not composed of cells.

Viruses do not have any cell structure at all.

Viruses are minutest particles with protein coat and nucleic acid. They do not have any cytoplasm inside. That is why they do not have any cell structure as in bacteria. Some bacteria and all viruses are obligate parasites. All viruses and some bacteria are filterable. Vis=rus reproduces like bacteria and have genes like bacteria.
