Protein Synthesis
What is protein synthesis?
an ongoing process by which cells make structural or functional proteins This process is one of the most important metabolic activities of a cell. The proteins it produces largely determine the structure and function of that cell.
What is the role of aminoacyl-tRNA synthetase in protein synthesis?
It binds the correct amino acid to a specific tRNA molecule. In order for protein synthesis to occur, each type of tRNA must be associated with its specific amino acid. Then the tRNA can bring that amino acid to the ribosome.
Which of the following must be present for transcription to occur?
RNA nucleotides Since transcription involves synthesizing an mRNA strand, RNA nucleotides must be present
How is the translation step of protein synthesis terminated?
The ribosome reaches a stop codon in the mRNA strand. When a stop codon (AUG, UAA, or UAG) enters the A site, the bond between the polypeptide and the tRNA is broken. The polypeptide is released and may then go through post-translational processing.
