EXAMPLE QUESTIONS
Q1. Pairs of homologous chromosomes:
- 1. separate in meiosis II
- 2. have genes for the same characters at the same loci
- 3. are found in gametes
- 4. have identical DNA sequences in their genes
Q2. Which of the following genotypes would produce the greatest variability of gametes if the alleles assorted independently?
- 1. AA Bb Cc Dd
- 2. Aa BB CC DD
- 3. Aa BB Cc Dd
- 4. Aa Bb Cc Dd
Q3. A circular DNA of 4.7 Mb (Mb=million base pairs) length is cut with a restriction enzyme whose precise recognition sequence is not known. The digest shows ~75 fragments on a pulsed-field gel. What is the most likely conclusion from this data?
- 1. The enzyme is an 8-base cutter.
- 2. The enzyme is a 6-base cutter.
- 3. The enzyme is a 4-base cutter.
- 4. This was a partial digest.
Q4. Which of the following techniques CANNOT be utilized to demonstrate Protein:Protein interaction?
- 1. Yeast three hybrid assay
- 2. Yeast two hybrid assay
- 3. Florescence resonance energy transfer (FRET)
- 4. Co-immunoprecipitation
Q5. Cyclins facilitate progression cell cycle by:
- 1. Inducing synthesis of constitutively active forms of growth cell receptors to trigger signalling cascades.
- 2. Activating the protein kinases which are critical regulators of cell division.
- 3. Increasing the production of DNA polymerases so cells can enter into G2 phase.
- 4. Directly activating G proteins which in turn affects the protein kinases
Q6. After mutagen treatment, a molecule of 2-aminopurine (an adenine analogue) incorporates into DNA. During replication the 2-AP protonates causing it to base-pair like guanine. The mutational event caused by this will be
- 1. AT to GC
- 2. AT to CG
- 3. GC to CG
- 4. GC to AT
Q7. Autoradiography of pulse-labelled cells can identify sites of biosynthetic activity and product accumulation. Identify the molecule and site of accumulation when a 5min [3H] uridine pulse followed by a 2-h chase in precursor-free media is given to the cells.
- 1. signals will be in only the nucleus because labelled DNA is continuously synthesized and accumulated
- 2. signals will be in the cytoplasm because labelled DNA is formed in the nucleus however accumulated in the cytoplasm over a longer period.
- 3. signals will be in the cytoplasm because labelled nuclear RNA is formed in the nucleus and then moves to the cytoplasm
- 4. signals will be in both nucleus and cytoplasm because labelled nuclear RNA will be continuously formed over 2 hours
Q8. An individual with the genotype AaBbccddEe can make how many different types of gametes?
- 1. two
- 2. three
- 3. eight
- 4. four
Q9. How do new alleles arise in a population?
- 1. Sexual reproduction
- 2. Meiosis
- 3. Chromosomal aberrations
- 4. Mutations of pre-existing alleles
Q10. How many linkage groups will be present in the human beings?
- 1. 24
- 2. 48
- 3. 23
- 4. 46
