In the presence of a chromogenic substrate,recombinant bacteria appear as .......

Following enzymes/chemical/technique are used in the process of gel electrophoresis:
$I.$ sample $DNA$ is cut into fragments
$II.$ restriction endonucleases
$III.$ agarose gel
$IV.$ ethidium bromide
$V.$ $UV$-radiation
$VI.$ elution
Mark the correct sequence of their use.

Which of the following processes is $NOT$ a part of the downstream processing?

After staining,the $DNA$ fragments can be seen on the gel by exposing them to.......... light,which appear as.......... colored bands.

What are the full forms of $ELISA$ and $PCR$?

Arrange the steps of $\text{rDNA}$ technology in the correct order$:-$
$(I.)$ Extraction of the desired gene product.
$(II.)$ Amplification of the gene of interest.
$(III.)$ Isolation of the desired $\text{DNA}$ fragment.
$(IV.)$ Ligation of the $\text{DNA}$ fragment into a vector.
$(V.)$ Insertion of $\text{rDNA}$ into the host.
The correct order is$:-$
