Answer:
C) Messenger RNA is transcribed from a single gene and transfers information from the DNA in the nucleus to the cytoplasm, where protein synthesis takes place.
Explanation:
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product, usually protein. Gene expression include steps such as
• transcription – part of DNA is copied into mRNA via an enzyme RNA polymerase
• RNA splicing – formed mRNA during transcription is not mature so it need to be proceed (e.g. excision of introns). Mature mRNA are then exported from nucleus to cytoplasm
• Translation – mRNA serves as information that codes for the synthesis of one or more proteins.
