Which best describes how scientists found the human gene that makes

insulin?

O

A. They found bacteria that could naturally produce insulin.

OB. They worked backward from DNA to mRNA.

O

C. They used the amino acid code to find the DNA base sequence.

O

D. They used the DNA sequence to find the protein sequence.

The best statement that describes how scientists found the human gene that makes Insulin is "They used the amino acid code to find the DNA base sequence".

Explanation:

Insulin is a hormone made by pancreas for the consumption of sugar into other form of energy. To find the human gene that makes insulin, scientists used the backward procedure.

They looked into the amino acid code and found the DNA base sequence. The initial startup began with mRNA that links the respective codon to the amino acid.
