Transcription- Turn DNA into mRNA

Translation- Turn mRNA into Protien

DNA’s Role-

Depends on which type!

1. mRNA *messenger RNA*

• Carries copies of DNA instructions for making proteins from the nucleus to ribosomes in the cytoplans

2. 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

3. 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.
