Question

when a gene is turned on they start to make their protein which is called?

Answer 1

this question is put in such a horrible way
do you understand even what its asking for?

Answer 2

It could be "DNA"
As Somy said, the question is put in a very unclear way, unless there were some word bank to pick from.

Though here is how a protein is normally formed in our bodies

during DNA replication there is transcription, and translation.
Transcription is when DNA makes RNA (m-RNA) ... than RNA during translation makes protein ( ribosomes synthesis protein).

Answer 3

the answer could simply be mRNA , since it's the last step to make the protein.
