Question

question 3 of 10
what aspect of bacteria makes recombinant dna technology effective?
a. bacteria only have mrna.
b. bacteria have insulin genes.
c. bacteria have no dna.
d. bacteria reproduce very quickly.

Explanation:

Bacteria's rapid reproduction is crucial for recombinant DNA technology. When foreign DNA (recombinant DNA) is inserted into bacteria, the quick reproduction means a large number of bacteria with the desired gene can be produced in a short time. This allows for mass - production of the proteins (like insulin) encoded by the inserted gene.

• Option A is incorrect because bacteria have DNA (genomic and plasmid) as well as mRNA.
• Option B is wrong as bacteria do not naturally have insulin genes (this is inserted via recombinant DNA technology).
• Option C is false since bacteria do have DNA (both genomic and plasmid DNA).

Answer:

D. Bacteria reproduce very quickly.
