One of the first breakthroughs in biotechnology was the discovery of the gene

that makes insulin. Part of this process involved scientists making DNA to

match each possible sequence of insulin mRNA. What was the next step of

this process?

A. Scientists found the DNA in the pancreas that matched the

manufactured DNA.

B. Scientists inserted pancreas DNA into bacterial cells.

C. Scientists mixed small portions of manufactured DNA with DNA

from the pancreas.

D. Scientists used the codon table to find the possible sequence of

mRNA.
