The blue and white selectable markers have been developed which differentiate recombinant colonies from non-recombinant colonies on the basis of their ability to produce colour in the presence of a chromogenic substrate.

Given below are two statements about this method:
Statement I : The blue coloured colonies have DNA insert in the plasmid and they are identified as recombinant colonies.

Statement II : The colonies without blue colour have DNA insert in the plasmid and are identified as recombinant colonies.

In the light of the above statements, choose the most appropriate answer from the options given below:

The maximum volume of air a person can breathe in after a forced expiration is known as

A metal block of base area \(0.2\; m ^{2}\) is connected to a \(0.02\; kg\) mass via a string that passes over an ideal pulley as shown in figure. A liquid film of thickness \(0.6\; mm\) is placed between the block and the table. When released the block moves to the right with a constant speed of \(0.17\; m / s\). The co-efficient of viscosity of the liquid is
