Codon
|
3 nucleotide bases
Found in mRNA ****Start codon: AUG**** |
|
|
Anti-codon
|
3 nucleotide bases
Found on the tRNA |
|
|
Transcription
|
First step in protein synthesis
Happens in the nucleus and takes DNA code and gets put on mRna (results) |
|
|
Translation
|
Second step in Protein Synthesis
Happens in the ribosome it gives us amino acids from the mRNA |
|
|

|
Amino acid chain connected by peptide bonds
|
|
|
mRNA
|
Messenger RNA
Carries the codons to the ribosome |
|
|
tRNA
|
Transfers the amino acids to the ribosome (carries the anti-codons)
|
|
|
