Q. No.
DNA polymorphism forms the basis of
1. Translation
2. Genetic mapping
3. DNA finger printing
4. Both genetic mapping and DNA fingerprinting
DNA fingerprinting involves identifying differences in some specific regions in DNA sequence called:
| 1. | Single nucleotides | 2. | Polymorphic DNA |
| 3. | Satellite DNA | 4. | Repetitive DNA |
Which is the basis of genetic mapping of the human genome as well as DNA fingerprinting?
1. Polymorphism in the DNA sequence
2. Single nucleotide polymorphism
3. Polymorphism in the hnRNA sequence
4. Polymorphism in the RNA sequence
2. Restriction enzymes
3. DNA –DNA hybridisation
4. Polymerase chain reaction
Satellite DNA is important because it:
| 1. | Codes for proteins are needed in the cell cycle. |
| 2. | Shows a high degree of polymorphism in the population and also the same degree of polymorphism in an individual which is inheritable from parents to children. |
| 3. | Does not code for proteins and is the same in all members of the population. |
| 4. | Codes for enzymes needed for DNA replication. |
PCR and Restriction Fragment Length Polymorphism are the methods for:
1. Study of enzymes
2. Genetic transformation
3. DNA sequencing
4. Genetic fingerprinting
What is it that forms the basis of DNA Fingerprinting?
| 1. | The relative difference in the DNA occurrence in blood, skin and saliva |
| 2. | The relative amount of DNA in the ridges and grooves of the fingerprints |
| 3. | Satellite DNA occurs as highly repeated short DNA segments |
| 4. | The relative proportions of purines and pyrimidines in DNA |
DNA or RNA segment tagged with a radioactive molecule is called:
| 1. | vector | 2. | probe |
| 3. | clone | 4. | plasmid |
Satellite DNA is a useful tool in:
1. Organ transplantation
2. Sex determination
3. Forensic science
4. Genetic engineering
