Polypeptide Synthesis - Translation Flashcards
What moves to the ribosome and pairs up with a sequence on the mRNA?
A tRNA molecule with the complimentary anticodon sequence, carrying an amino acid
What attaches to the starting codon at one end of the mRNA molecule?
A ribosome
What pairs with the next codon on the mRNA?
Another tRNA with a complimentary anticodon, carrying an amino acid
What moves along the mRNA strand bringing together the tRNA molecules?
The ribosome
How are peptide bonds formed between the amino acids on the tRNA molecules?
By means of an enzyme and ATP
As the ribosome moves along the mRNA strand, what is released and why?
tRNA molecules behind the movement of the ribosome are released to collect another amino acid
The synthesis of a polypeptide continues until which point?
Until the ribosome reaches a stop codon
What happens to the polypeptide after translation that determines what protein is made?
It is coiled or folded to produce its secondary structure; Then folded further to produce the tertiary structure and then sometimes are linked with other polypeptide chains and non-protein groups to form the quarternary structure
