Study Notes

Gene Expression

Gene expression involves two essential steps: transcription and translation

Transcription

Occurs in the nucleus of eukaryotes
Involves the synthesis of mRNA using the gene on the DNA molecule as a template

Translation

Involves the synthesis of a polypeptide chain using the genetic code on the mRNA molecule as a guide
Relies on the mRNA molecule as its template

RNA (Ribonucleic Acid)

Found throughout the cell, including:
- Nucleus
- Mitochondria
- Chloroplasts
- Ribosomes
- Soluble part of the cytoplasm
Types of RNA:
- Messenger RNA (mRNA)
