In recombinant DNA technology, restriction enzymes are used
Select one:
a.As molecular glue
b.None of the above
c.To make thousands of new copies of genes of interest
d.To decode DNA into mRNA
c. To make thousands of new copies of genes of interest
The correct answer is c. To make thousands of new copies of genes of interest.
Restriction enzymes, also known as restriction endonucleases, are enzymes that are used in recombinant DNA technology. These enzymes recognize specific DNA sequences and cut the DNA at those sequences. This ability to cut DNA at specific sites allows scientists to insert genes of interest into plasmids or other vectors.
By using restriction enzymes, scientists can cut the DNA containing the gene of interest and the vector at specific sites, and then join the two pieces together using DNA ligase. This results in the creation of recombinant DNA, which contains the gene of interest inserted into the vector.
Once the recombinant DNA is created, it can be introduced into host cells, such as bacteria, where it can replicate and produce thousands of copies of the gene of interest. This process, known as gene cloning, allows scientists to obtain large amounts of the gene for further study or use in various applications.
Therefore, the correct answer is c. To make thousands of new copies of genes of interest.
