BIOD 210 Module 4 Exam (Latest Update
) Genetics | Questions & Answers |
Grade A | 100% Correct. Portage Learning.
1. Structural gene: genes not involved in the bio-regulation but rather
structure of enzyme
2. prophage DNA:: virus DNA embedded in the host cell's DNA
3. temperate phage: a phage capable of either lysis or acting as a
prophage within a bacterial cell
4. Inducible gene: a gene whose expression is turned on in the presence.
5. gratuitous inducer of lac operon: IPTG
6. lacZ: - b-galactosidase
- converts lactose to glucose and galactose
7. lacY: - permease
- lactose transport into bacterial cell
8. lacA: - transacetylase
- may remove toxins

9. A ______ phage will always lyse its host cell.: virulent
10. A prophage will integrate into the bacterial __________.:
chromosome
11. A phage capable of lysis or integration is a ______ phage.:
temperate
12. Log phase:: The period of exponential growth of bacterial
population.
13. Lag phase:: Initial phase with no cell division.
