Answer:
b. Bacteria with the desired plasmid produce white colonies.
Explanation:
The bacterial lacZ gene is usually used as a reporter gene, which encodes beta-galactosidase, an enzyme that breakdown lactose but can also breakdown a colourless synthetic analog X-gal, thereby producing blue colonies on X-gal–containing media. But the lacZ will be disabled when the recombinant DNA is spliced into the plasmid. This is because the LacZ protein will not be produced when the gene is disabled. Thus, X-gal will not be broken down and white colonies will be produced, which can then be separated and identified.

Answer:
Explanation:
From the given information; It is pertinent to understand that hIgh mass stepping stool comparing to polyubiquitination of protein is gotten when each and every constituent of the chemical enzymes are added to the in-vitro framework. In view of these outcomes, it is obvious that E1, E2, and E3 ligase are needed for ubiquitination.
Answer:
Viruses come in many different structures. ... All of these viruses would still have genetic material, either in the form of DNA or RNA. They also would have a protein coat known as a capsid. However, some of these viruses may have an envelope in addition, which covers the capsid (such as the influenza virus).
