What is the Function of the Translation Repressor Protein

Question

What is the function of the translation repressor protein?
A)It binds to a gene on the DNA and prevents translation.
B)It binds to a master developmental regulatory gene and prevents translation.
C)It binds to amino acids and prevents them from forming the protein chain.
D)It binds to a proteasome and prevents translation.
E)It binds to a mRNA and prevents translation from that mRNA.

Accepted Answer

A translation repressor protein attaches to the beginning of the mRNA,making it impossible for mRNA to bind to a ribosome (and therefore prevents translation of the encoded protein).If the correct signal or chemical binds the translation repressor protein,then the mRNA is released and translation begins.
