Which of the following technique is used to identify between two species?
a) DNA fingerprinting
b) DNA sequencing
c) polymerase chain reaction
d) DNA synthesis
Which of the following was the first method used in DNA analysis?
a) restriction fragment length polymorphism (RFLP)
b) DNA sequencing
c) polymerase chain reaction (PCR)
d) DNA synthesis
Explanation: restriction fragment length polymorphism is a technique that exploits variations in homologous DNA sequences, known as polymorphisms, populations, or species or to pinpoint the locations of genes within a sequenc

b) three
c) four
d) five
Explanation: collection DNA samples, placement of RFLP, separation of RFLP, southern blotting and autoradiography
