Question

2. What enzyme makes mRNA? Does this enzyme read the base sequence of the gene? 3. In translation, the reads the base sequence of to make 4. Expression of a gene that codes for tRNA involves both transcription and translation. A. true B. false 5. During the elongation stage/step of translation, the ribosome reads the codon sitting in its site (A- site, P-site or E-site, pick one). 6. What brings amino acids to the ribosome during translation? A. tRNA B. mRNA C. rRNA D. DNA E. primer 7. the gene encoding for a certain ribosomal protein is expressed ALL the time. This is an example of a gene. A. regulated B. mutated C. wildtype D. constitutive 8. the codon ACC specifies which amino acid (ie- which amino acid would the ribosome put into the protein after reading ACC on the mRNA)? 9. An amino acid is specified by only ONE codon. A. true B. false 10. The anticodon of the binds to the of the mRNA. 11. The event in #10 occurs during a. replication b. transcription c. translation d. mutation 12. Does the codon UAG specify and amino acid? What happens to translation when ribosome reads this codon? 13. Name the 2 conditions that must be met for the lac operon to be turned on? Describe what each condition does to the operon (1-2 sentences at most).
