Question

One of the first breakthroughs in biotechnology was the discovery of the gene that makes insulin. The first step of this process was using a codon table to find the possible sequence of mRNA for insulin. What was the next step of this process?

A. Scientists inserted pancreas DNA into bacterial cells.
B. Scientists mixed small portions of manufactured DNA with DNA from the pancreas.
C. Scientists found the DNA in the pancreas that matched the manufactured DNA.
D. Scientists made DNA to match each possible sequence of mRNA.

Answer 1

The correct answer is option D, Scientists made DNA to match each possible sequence of mRNA

Step-by-step explanation:

The correct procedure of making insulin is as follows -

1. From the pancreas cell, the human insulin producing gene is extracted

2. Then the possible sequence of mRNA for insulin is derived

3. DNA of bacteria along with restriction enzyme is used to form the recombinant DNA of human insulin-producing gene

4. This recombinant DNA is then inserted into the bacterium

5. The bacteria with recombinant DNA multiplies to form human insulin .

Answer 2

The best and most correct answer among the choices provided by the question is the fourth choice. The next step of the process was that scientists made DNA to match each possible sequence of mRNA.I hope my answer has come to your help. God bless and have a nice day ahead!
