Consider the following statements:
I. The largest known human gene is dystrophin at 2.4 million bases
II. Repeated sequences make up very large portion of the human genome
III. There are about 2.4 million locations where single base DNA differences occur in humans
Which of the above statements are true?
1. I and II only
2. I and III only
3. II and III only
4. I, II and III
Which of the following is not required for any of the techniques of DNA fingerprinting available at present ?
(1) Zinc finger analysis
(2) Restriction enzymes
(3) DNA-DNA hybridisation
(4) Polymerase chain reaction
Satellite DNA is important because it
1. codes for protiens needed in cell cycle
2. shows high degree of polymorphism in population and also the same degree of
polymorphism in an individual, which is heritable from parents to children
3. does not code for protiens and is 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
Satellite DNA is useful tool in
(1) organ transplantation
(2) sex determination
(3) forensic science
(4) genetic engineering
