Assertion : In recombinant DNA technology, human genes are often transferred into bacteria (prokaryotes) or yeasts (eukaryotes). Reason : Both bacteria and yeasts multiply very fast to form huge populations which express the desired gene.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIfboth assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
A. If both assertion and reason are true and reason is the correct explanation of assertion.
Step-by-step solution
In recombinant DNA technology, widely used hosts for replication and amplification of recombinant DNA are prokaryotic E. coli and the eukaryotic yeast. They replicate very fast to form huge populations which express the desired gene. Yeast artificial chromosomes (YACs) 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.
