Biotechnology : Principles And Processes

Question
CBSEENBI12047006

Assertion : In recombinant DNA technology, human genes are often transferred into bacteria (prokaryotes) or yeast (eukaryote).

Reason : Both bacteria and yeast multiply very fast to form huge populations which express the desired gene.

  • If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion

  • If both Assertion and Reason are true but the Reason is not the correct explanation of the assertion

  • If Assertion is true but Reason is false.

  • If both Assertion and Reason are false

Solution

A.

If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion

In recombinant DNA technology, prokaryotic E. coli and eukaryotic yeast is the widely used host for replication and amplification of recombinant DNA. They replicate very fast in order to form a large population that express a desired gene.

Yeast artificial chromosome (YAC) is an important cloning tool for the analysis of complex genome such as that of humans. They allow the maintenance, propagation and analysis of such genome in an experimentally tractable system.
