Scales of a fish, I kind of read or heard people getting drafts of fish skin which might be the same.
<span>Scientists who wish to clone genes of interest into bacterial plasmids utilize
restriction enzymes, which cuts the target and vector DNA at specific sites. then
DNA ligase is used to form covalent bonds between the resulting fragments to complete the recombinant DNA molecule.
</span>
<span>Restriction enzymes (endonucleases) are enzymes which recognize specific target sequences (recognition sites) and will make a double-stranded cut in the DNA molecule at or near recognition sites.</span>
DNA ligase is an enzyme which uses ATP to link two DNA molecules if they have matching ends.
Answer:
The correct answer is b. I and II
Explanation:
Sexual reproduction is present in higher forms of life and absent in prokaryotes like bacteria. Sexual reproduction results in greater evolutionary changes due to the fusion of two different gametes from two different individuals of a species.
Therefore sexual reproduction helps in increased genetic diversity in higher forms of life. In prokaryotes like bacteria, genetic diversity is maintained and increased through DNA transfer from one bacterial cell to another with the help of a process known as horizontal gene transfer.
Bacteria have sex pilli which is used to introduce the genes to the other bacteria. By this process, they increase their genetic diversity and evolve continuously. So the correct is b. I and II.
