Bitesize GCSE Biology - Series 1: The Cell - Protein Synthesis

Episode 5 - Protein Synthesis

Overview

• Released on: March 23, 2023
• Duration: 8 minutes
• Topic: How proteins are made during the processes of transcription and translation.

Key Concepts

Protein Synthesis

• Definition: The process by which cells make proteins.
• Importance: Proteins are crucial for many cellular functions and structures.

Transcription

• Location: Occurs in the cell nucleus.
• Process:
  • The DNA sequence of a gene is copied into messenger RNA (mRNA).
  • RNA polymerase is the key enzyme involved.
  • mRNA serves as a template for protein synthesis.

Translation

• Location: Takes place in the cytoplasm of the cell.
• Process:
  • mRNA is translated into a chain of amino acids, forming a protein.
  • Ribosomes facilitate the translation process.
  • Transfer RNA (tRNA) brings amino acids to the ribosome, matching the sequence of the mRNA.
