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
