Study Notes
Gene Expression
- Gene expression involves two main steps: transcription and translation
Transcription
- Occurs in the nucleus of eukaryotes
- Synthesizes mRNA using the gene on the DNA molecule as a template
Translation
- Uses the genetic code on the mRNA molecule as its guide
- Synthesizes a polypeptide chain
Ribonucleic Acid (RNA)
- Found throughout the cell, including: • Nucleus • Mitochondria • Chloroplasts • Ribosomes • Soluble part of the cytoplasm
Types of RNA
- Messenger RNA (mRNA)
