C
The breakdown of RNA molecules in the cytoplasm
D
The process by which genetic information is used to synthesize proteins
Verified step by step guidance1
Understand that gene expression is the process by which information from a gene is used to synthesize a functional gene product, typically proteins.
Recognize that gene expression involves two main stages: transcription and translation.
During transcription, the DNA sequence of a gene is transcribed to produce a complementary RNA molecule. This occurs in the nucleus of eukaryotic cells.
In translation, the RNA molecule is used as a template to assemble amino acids into a polypeptide chain, forming a protein. This occurs in the cytoplasm at the ribosome.
Gene expression is crucial for cellular function and regulation, allowing cells to respond to changes in their environment and perform specific functions.
