Answer #1

The correct answer will be (B), (C), (D), (F).

Explanation :-

(B), (C), (F) are correct answers because three principal mechanisms can mediate horizontal gene transfer: transformation (uptake of free DNA), conjugation (plasmid-mediated transfer), and transduction (phage-mediated transfer).

(D) is correct answer because A transposable element is a mobile segment of DNA that can sometimes pick up a resistance gene and insert it into a plasmid or chromosome, thereby inducing horizontal gene transfer of antibiotic resistance.

(A) is wrong answer because it has written mutated genes which is wrong because mutated genes are not transferred through horizontal gene transfer.

(E) is wrong answer because it has written capsule biosynthesis genes which is wrong because capsule biosynthesis genes are not transfer through horizontal gene transfer.

7)  Select the true statements about how bacteria can get new genetic material.  Circle all that apply. Conjugation can occur only between bacteria of the same species. In transformation, bacteria can pick up pieces of bacterial DNA from their surroundings. It is necessary for viruses to be lysogenic for restricted transduction to occur. In transduction, bacterial genes end up in viral capsids. Bacterial conjugation can use pili, which act as pseudopods, engulfing genes from another bacterium to incorporate them into the cell’s...
