Question

One of the first breakthroughs in biotechnology was the discovery of the gene that makes insulin. What was the first step of this process?

A. Scientists used the codon table to find the possible sequence of mRNA
B. Scientists mixed small portions of manufactured DNA with DNA from the pancreas
C. Scientists made DNA to match each possible sequence of mRNA
D. Scientists found the DNA in the pancreas that matched the manufactured DNA

Answer 1

Answer:d

Explanation:it’s right

Answer 2

The correct answer is option C, that is, scientists made DNA to match each possible sequence of mRNA.

Step-by-step explanation:

In order to produce insulin, the human insulin-producing gene is extracted from the pancreas cell, after that the probable mRNA sequence for insulin is obtained. The bacterial DNA along with the restriction enzyme is utilized to produce the recombinant DNA of the human insulin-generating gene. The recombinant DNA is then presented into the bacterium, the bacteria comprising recombinant DNA then proliferate to produce human insulin.
