D
Explanation:
answers A-C are choices that explain a substances physical change NOT chemical. Decomposition is where the chemical structure of a compound will breakdown to smaller molecules.
The process of gene expression involves two main stages:
Transcription: the production of messenger RNA (mRNA) by the enzyme RNA polymerase, and the processing of the resulting mRNA molecule.
Translation: the use of mRNA to direct protein synthesis, and the subsequent post-translational processing of the protein molecule.
Some genes are responsible for the production of other forms of RNA that play a role in translation, including transfer RNA (tRNA) and ribosomal RNA (rRNA).
