The glow-in-the-dark trait gene:
a. comes from a firefly
b. comes from e. coli
c. could be used in anti-hiv drug development
d. a and c

The correct answer for: The glow-in-the-dark trait gene: Is: a) comes from a firefly.

Explanation:

First of all, we need to make clear something. E. coli can glow in the dark if we add a chemical element. As well as an anti-HIV could glow in the dark by adding something. However, it is not naturally attached as a gene. In this case, the only thing that can glow naturally in the dark without anything else is the firefly. So, it carries that gene. In chemistry, we could make everything glow in the dark but naturally, a gene represents cero manipulation.

the correct answer is b

thinking it would be physical characteristics
