Sometimes a newly folded protein must be modified before becoming functional. What level of gene control is this?

A) transcriptional
B) posttranscriptional
C) translational
D) posttranslational
E) operon

Posttranslational

Refers to the chemical modifications and processes occurring to a protein after it has been synthesized by ribosomes.

Translational

Pertaining to the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis.

Posttranscriptional

Pertains to the alterations and processes that RNA molecules undergo after they are transcribed from DNA but before they are translated into proteins.
