Questions of the Week
Note: Questions of the week are given at the end of labs 1, 3, 5, 6, 7, 9, 10, 12, 13, 14
- Question of the Week No. 1: Mitosis
- Answer: Top left clockwise: Daughter cells, Prophase, Anaphase, Metaphase, Interphase, Anaphase,
- In the figure below: Spindle fibers
- Question of the Week No. 2: Restriction Mapping
- Answer: Circular.
- In linear configuration, fragment sizes generated after digesting the DNA with BamHI must be 5505, 16841, 5626, 6527, 7233, and 6770 bp. On the gel, the two fragments 5505 and 6770 are missing, instead a fragment of 12275 bp appears. This is the sum of the 5505 and 6770 from the two extreme ends of the DNA, which indicates that the DNA is circular.
- Deduced sequence:
- 5' GCTAGGCGTATGACTGTGATCTAGTATCGAACTA 3'
- 3' CGATCCGCATACTGACACTAGATCATAGCTTGAT 5'
- Question of the Week No. 4: Cloning 1
Question of the Week No. 5: Cloning 2
- Answer: (a) EcoRI
- (b) EcoRI
- (c) Kanamycin.
- Ampicillin cannot be used because when the gene of interest is inserted into the vector via the
- EcoRI site, it interrupts the amp-r gene, thus destroys its function.

- Question of the Week No. 8: Crossing Over
- Question of the Week No. 9: Complementation Test
