The correct sequence of different steps of polymerease chain reaction is
1) annealing → denaturation → extension
2) denaturation → extension → annealing
3) denaturation → annealing → extension
4) extension → denaturation → annealing

A

1) annealing `rarr` denaturation `rarr` extension

B

2) denaturation `rarr` extension `rarr` annealing

C

3) denaturation `rarr` annealing `rarr` extension

D

4) extension `rarr` denaturation `rarr` annealing

Text Solution

Verified by Experts

The correct Answer is:
C
Polymerase chain reaction is a technique used to replicate a fragment of DNA so as to produce many copies of a particular DNA sequence. A single PCR amplification cycle involves three basic steps : denaturation, annealing and extension (polymerisation).

Study carefully the following stages of life cycle of malarial parasite i.e., Plasmodium. Arrange these stages in the correct sequence and select the correct answer. 1. Sporozoites leave the blood stream and enter the liver cells of man. 2. Sporozoites present in the salivary glands of female Anopheles mosquito are injected into the blood stream of man. 3. The parasite reproduces asexually in RBCs, resulting in bursting of RBCs and causing the cycles of fever, relased parasites infect new RBCs. 4. The parasite reproduces asexually in liver cells, ultimately causing the rupturing of cells. 5. Two types of gametocytes i.e., microgametocytes and macrogametocytes develop in the RBCs. 6. Female Anopheleles mosquito takes up the gametocytes with blood meal of an infected person. 7. Mature infective stage of the parasite i.e., sporozoites escape from intestine and migrate to the mosquito's salivary glands. 8. Fertilisation and developmental stages of the parasite take place in mosquito's stomach.
