Protein synthesis Flashcards
1
Q
What are the 2 stages of protein synthesis?
A
Transcription
Translation
2
Q
What is transcription?
A
Occurs in the nucleus
DNA is read by enzymes and used to make a single-stranded mRNA molecule
Then leaves the nucleus through a nuclear pore and travels to a ribosome in the cytoplasm or RER
3
Q
What is translation?
A
Occurs at a ribosome
mRNA attaches to the ribosome and a tRNA molecule brings a specific amino acid
Ribosomal enzymes catalyse the formation of peptide bonds between adjacent amino acids to form the primary structure of a new polypeptide
