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)
