DNA and RNA Structure MCQs part 2

1. The technique involved in comparing the DNA components of two samples is known as

• Monoclonal antibody techniques
• Genetic finger printing
• Recombinant DNA technology
• Polymerase chain reaction

2. Plasmids are ideal vectors for gene cloning as

• They can be multiplied by culturing
• They can be multiplied in the laboratory using enzymes
• They can replicate freely outside the bacterial cell
• They are self replicating within the bacterial cell

3. Humans normally have 46 chromosomes in skin cells. How many autosomes would be expected in a kidney cell?

• 46
• 23
• 47
• 44

4. Pasteur effect is due to

• Change from aerobic to anaerobic
• Providing oxygen to anaerobically respiring structures
• Rapid utilization of ATP
• Nonsynthesis of ATP

5. A mechanism that can cause a gene to move from one linkage group to another is

• Trans location
• Inversion
• Crossing over
• Duplication

6. The smallest unit of genetic material that can undergo mutation is called

• Gene
• Cistron
• Replicon
• Muton

7. The two chromatids of metaphase chrosome represent

• Replicated chromosomes to be separated at anaphase
• Homologous chromosomes of a diploid set
• Non-homologous chromosomes joined at the centromere
• Maternal and paternal chromosomes joined at the centromere

8. Malate dehydrogenase enzyme is a

• Transferase
• Hydrolase
• Isomerase
• Oxido reductase

9. In E.Coli att site is in between

• Gal and biogenes
• Bio and niacin genes
• Gal and B genes
• None of these

10. The best vector for gene cloning

• Relaxed control plasmid
• Stringent control plasmid
• Both a and b
• None of these
