QUESTIONS (TRUE/FALSE):
1. The same enzyme may be responsible for cutting DNA and for 'fusing' DNA.
2. The sequence of base pairs determines where an enzyme will cut the DNA.
3. For this demonstration; genes are like words.
4. The length of a strip of paper does not determine the grammar of its sentence.
5. The interaction of several mechanisms cause genetic re-arrangement.
6. Once a gene has been moved it can never move back to its original position.
7. The same processes that move genes within a chromosome may move genes between chromosomes.
8. Insects have a higher mutation rate than bugs.
9. A gene against mutation is more likely to remain stable over time.
10. The size of a chromosome does not determine its genetic viability.

ESSAY:
16. What are some of the factors that determine whether any re-arrangement of genetic material is viable or non-viable?
17. Explain how a random process (such as cutting a chromosome) may lead to an ordered gene structure.
18. What is lysis and why is it site specific?
19. Did anyone tape their strips together backwards? What are the genetic implications of this?
20. Why use sentence syntax to describe genetic syntax?
