Q177 / 180 · AIIMS 2005 · Zoology

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.

  • Correct answer
    A
    If both assertion and reason are true and reason is the correct explanation of assertion
  • B
    If both assertion and reason are true but reason is not the correct explanation of assertion
  • C
    If assertion is true but reason is false
  • D
    If both assertion and reason are false.

Solution

In recombinant DNA technology widely used host for replication and amplification of recombinant DNA are prokaryotic $E$. coli and the eukaryotic yeast. They replicate very fast to form a large population which expresse desired gene. Yeast artificial chromosome (YAC) are important cloning tools 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, the yeast.

Hence, the correct answer is option: 'A'.
