Question

I put the human insulin gene into a plasmid and put that plasmid into a bacteria. But the bacteria doesn't produce the insulin. What should I have put before the human insulin gene on the plasmid to make sure it made insulin?

A. Cap
B. A Promotor site
C. Tail
D. DNA polymerase

Answer 1

The correct answer is B. A Promoter site.

Step-by-step explanation:

In order for a gene to be expressed, it needs to be transcribed into RNA and then translated into a protein. The process of transcription is initiated by RNA polymerase binding to a promoter site, which is a specific sequence of DNA that signals the start of a gene.

Hope it helps!
