Protein Synthesis 14.1-14.2
Transcription- Turn DNA into mRNA
Translation- Turn mRNA into Protien
\ DNA’s Role-
Depends on which type!
- mRNA *messenger RNA*
- Carries copies of DNA instructions for making proteins from the nucleus to ribosomes in the cytoplans
\n
- rRNA *ribosomal RNA*
- Makes up major part of ribosomes
- Site of protein production
- Works by reading (TRANSLATING) the mRNA code into a protein
- Brings together mRNA and tRNA, linking amino acids together with a peptide bond
\n
- tRNA *transport RNA*
- Consists of two parts- amino acids and anticodon (3 unpaired bases)
- transfer / carrier amino acids from the cytoplasm to the ribosome and matches them to coded mRNA messages.
