Supet Tet Vaccany

A leaf electroscope is a simple apparatus to detect any charge on a body. It consist of two metal leaves OA and OB, free to rotate about O. Initially both are very slighty separted. When a charged object is touched to the metal knob at the top of the conduction re, charge flows from knob to the top of the conduction rod, charge flows from knob to the leaves through the conducting rod, charge flows from knob to the leaves through the conduction rod. As the leaves are now charged similarly, they start repelling each other and tet separted (deflected by certain angle). The angle of deflection in static equilibrium is an indicator of the amount of charge on the charged boy. If we perform these steps one by one. In which case, the leaves will converge (come closer), as compared to the previous state?

The angle of deflection in static equilibrium is an indicator of the amount of charge on the charged boy. When a+20C rod is touched to the knob, the deflection of leaves was 5^(@) , and when an identical rod of -40C is touched, the deflection was found to be 9^(@) . If an identical rod of +30C is touched, then the deflection may be:

A typical angiospermic anther is bilkobed and tet ragonal consisting of

In pBR322, tetracycline resistance gene (tet^(R)) has recognition site for which of the following restriction endonuclease ?

Which one of the following restriction enzyme can cut "Tet"^R site of pBR322 ?

Assertion: E. coli having pBR322 with DNA insert at BamHI site cannot grow in medium containing tetracycline. Reason: Recognition site for Bam HI is present in "tet"^(R) region of pBR322.

(a) In pBR322, foreign DNA has to be introduced in Tet^(R) region. From the restriction enzymes given below, which one should be used and why: Pvul, EcoRI, BamHI. (b) Give reasons, why the other two enzymes cannot be used.

Tet f be continuous on [a,b] and differentiable on (a,b). If f(a)=a and f(b)=b, then
