Question 17
Bacteria were some of the first organisms to be genetically modified because they have a relatively small genome and reproduce quickly. All the following are reasons to study and modify a bacterial cell's genome for beneficial uses except

a
to determine genes that code for toxins against other bacterial cells to make antibiotics from these toxins.
b
to use bacteria cells as a vector to add genes that code for useful products.
c
to modify bacteria into an infectious form that has the ability to mutate quickly.
d
to determine the genes that code for proteins such as those used to produce insulin in large amounts.

a
The bacterium will produce insulin at a fast rate by incorporating the gene into its own genetic code.
b
The bacterium will quickly destroy the insulin gene and create a replacement, which is free of mutations.

I can’t determine Q16 without the diagram — please upload the image or describe how W, X and Y change the sequence (e.g., which bases are added, removed, or replaced).

Answers for Q17–Q25:
17. C — to modify bacteria into an infectious form that mutates quickly (not a beneficial reason)
18. A — nucleus (viruses do not have nuclei)
19. B — photosynthesis
20. A — amino acids
21. A — the bacterium will produce insulin quickly by using the inserted gene
22. B — insulin and growth hormones
23. D — DNA analysis distinguishes individuals because their DNA is unlikely to be the same
24. C — “All cells arise spontaneously” (this is not part of cell theory)
25. C — deletion; yes (it causes a frameshift)
