Protein Synthesis
Question | Answer |
---|---|
Be able to Identify the order of the steps involved in protein synthesis, in translations (1-3) | 1. The mRNA molecule arrives at the synthesis site 2. A tRNA molecule bearing a specific amino acid arrives at the ribosome 3. A second tRNA molecule arrives at the ribosome |
Be able to Identify the order of the steps involved in protein synthesis, in translations (4-5) | 4. A pair of amino acids bond together to form a dipeptide molecule 5. A polypeptide is completed. |
Be able to identify the order of the steps involved in protein synthesis, in transcription | 1. A transcription factor bonds to a promoter site 2. RNA polymerase attaches and the gene in unwound 3. Acting as a template, DNA produces an mRNA molecule 4. A strand of mRNA exits the nucleus and move out into the cytoplasm |
What is the structural and functional definition of the term "gene" | A sequence of DNA molecules that encodes for a specific polypeptide or mRNA sequence |
