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

You have identified a useful gene in bacteria. Make a flow chart of the steps that you would follow to transfer this gene to a plant.

Downstream processing includes:
$I.$ Separation of the product from the reactor
$II.$ Purification of the product
$III.$ Formulation of the product with suitable preservatives
$IV.$ Quality control testing and clinical trials in case of drugs
Which of the statements given above are correct?

Palaeontologists unearthed a human skull during excavation. $A$ small fragment of the scalp tissue was still attached to it. Only a little $DNA$ could be extracted from it. If the genes of the ancient man need to be analysed,the best way of getting a sufficient amount of $DNA$ from this extract is:

Which of the following range of temperature is required for denaturation,annealing of primer,and primer extension of $PCR$ respectively?

Given below are four statements pertaining to the separation of $DNA$ fragments using gel electrophoresis. Identify the incorrect statements:
$(a)$ $DNA$ is a negatively charged molecule and so it is loaded on the gel towards the Anode terminal.
$(b)$ $DNA$ fragments travel along the surface of the gel,whose concentration does not affect the movement of $DNA$.
$(c)$ The smaller the size of the $DNA$ fragment,the larger is the distance it travels through it.
$(d)$ Pure $DNA$ can be visualized directly by exposing it to $UV$ radiation.
