5.3 PROTEIN SYNTHESIS :

TRANSCRIPTION

Learning Outcome

1

  • Overview of the relationship between DNA and Protein Synthesis
  • Explain transcription which involves RNA polymerase to form mRNA

Protein Synthesis

2

  • Protein synthesis is a process by which living cells synthesize protein

  • Consists amino acids sequence according to genetic information carried in DNA and RNA

Diagram

1) Synthesis of mRNA in the nucleus

2) Movement of mRNA into cytoplasm via nuclear pore.

3) Synthesis of protein.

INITIATION

TRANSCRIPTION

  • RNA polymerase binds to promoter (at TATA box) and then unwind the DNA strands.
  • RNA polymerase initiates mRNA synthesis by adding RNA neucleotides that complementary to the template strand (DNA)

  • A process by which genetic information on DNA is transcribed to form mRNA
  •  Occur in nucleus.

ELONGATION

ELONGATION

  • RNA polymerase moves downstream,unwinding the DNA and elongating RNA transcript from 5' - 3' by adding nucleotides to the 3' end of growing polynucleotides
  • RNA polymerase moves downstream,unwiding the DNA and elongating RNA transcript from 5' - 3' by adding nucleotides to the 3' end of growing polynucleotide

TERMINATION

Transciption terminates when RNA polymerase reaches 'stop signal' at terminantion site.

mRNA is released and the RNA polymerase detach from DNA
