Question

Which of the following is the correct sequence of steps in genetic engineering?. . a. cut DNA, recombinant DNA, cloning, screening. b. screening, cut DNA, recombinant DNA, cloning. c. screening, cloning, recombinant DNA, cut DNA. d. cut DNA, cloning, recombinant DNA, screening

Answer 1

Answer: A
The sequence of steps in genetic engineering is as follows:
I) DNA is cut into fragments
2) These fragments of DNA are attached to the vectors for the formation of Recombinant DNA
3) Third step is cloning of the Recombinant DNA to get as many copies of recombinant DNA as possible
4) Screening of the new DNA produced.

Answer 2

The correct answer is a. cut DNA, recombinant DNA, cloning, screening

When the DNA is isolated, you cut it and remove it from the organism, followed by making recombinant DNA, which is followed by cloning and screening.
