Transcription and Translation

• RNA Transcription


  The process of converting the coding region of DNA into mRNA
• RNA


  • Polymerase
  • Coding region of DNA is converted to mRNA
  • Non-template strand of DNA

  Template strand of DNA
• RNA Transcription


  1. DNA unravels

  2. RNA nucleotides match up with one side of the DNA

  3. mRNA strand leaves the nucleus
• Translation information in the nucleotide base sequence of mRNA is used to dictate the amino acid sequence of a protein
• Growing polypeptide chain


  • Ribosome
  • tRNA
  • Amino acid
• A section of DNA (a gene) is transcribed into RNA
