NEET (UG) 2023 — Question 117
Main steps in the formation of Recombinant DNA are given below. Arrange these steps in a correct sequence.
A. Insertion of recombinant DNA into the host cell.
B. Cutting of DNA at specific location by restriction enzyme.
C. Isolation of desired DNA fragment.
D. Amplification of gene of interest using PCR.
Choose the correct answer from the options given below :
- Option A:
- Option B:
C,B,A,D
- Option C:
- Option D:Correct
Answer: D
Step-by-step solution
The correct answer is option (4) because recombinant DNA technology involves several steps in
specific sequence such as isolation of DNA, fragmentation of DNA by restriction endonucleases,
isolation of desired DNA fragment, ligation of the DNA fragment into a vector, transferring the
recombinant DNA into the host, culturing the host cells in a medium at large scale and extraction
of the desired product.
