QUESTION 4 The biochemical pathway driven by the proteins encoded by the lac operon is an example of a biosynthetic pathway. ? True False QUESTION 5 Which of the following types of gene regulation contribute to the regulation of the trp operon (select all that apply)? Autoregulation Positive regulation Use of translation to regulate transcription ul Repressible negative transcriptional regulation Inducible negative transcriptional regulation QUESTION 6 When tryptophan levels are high, the trp mRNA takes on the antiterminator configuration. @) True O False QUESTION 7 Which of the following mechanisms of gene regulation can increase the size of the proteome without increasing the size of the genome? Alternative splicing 9 Post-translational modification CRC activity O SiRNA

Explanation / Answer

4. FALSE

Lac operon codes for enzymes required for the catabolism of lactose.

5. Options C and D are correct.

Trp operon is an example repressible negative regulation.

6. FALSE

When Trp levels are low, the trp mRNA takes on the anti-terminator configuration

7. Option A is correct.

Alternative splicing can increase proteome without affecting the genome.
