During the purification process for recombinant $DNA$ technology,the addition of chilled ethanol precipitates out:

The preparatory phase before fermentation is known as:

Recombinant $\text{DNA}$ is directly injected into the nucleus of an animal cell by $-$

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$:-$

Which of the following is used for direct gene transfer?

Can you think and answer how a reporter enzyme can be used to monitor transformation of host cells by foreign $DNA$ in addition to a selectable marker?
