Options

A. If any protein encoding gene is expressed in a homologous host, it is called a recombinant proteins
B. In PCR, the multiple copies of gene of interest is synthesised in vitro using one set of primers
C. A thermostable enzyme (Taq polymerase) is obtained from cyanobacterium Thermus aquaticus
D. None of the above

Answer

D

Explanation

`**` If any protein encoding gene is expressed in a heterologous host, it is called a recombinant protein.
`**` In PCR, the mutiple copies of gene of interest is synthesised in vitro using two set of primers.
`**` A thermostable (Taq polymerase) is obtained from bacterium Thermus aquaticus
