A foetal genetic disorder can be studied by which of the following?

Which of the following is not a venereal disease?

Alcohol is a depressant, which means that even small amounts of alcohol slow down the actions of parts of the brain, so alcohol lengthens the time you take to respond to a stimulus.
Different people react differently to alcohol. In some people, it increase their feelings of aggression, and releases their inhibitions so that they are more likely to be violent or commit other crimes.
An alcoholic needs to drink quite large quantities of alcohol regularly. This causes many parts of the body to be damaged, because alcohol is poisonous to cells. Probably, there are many factors which decide whether or not a person becomes alcoholic. Over a long period of time, it can cause loss of memory and confusion. One way in which the damage is done is that alcohol in the body fluids draws water out of cells by osmosis.
Identify the measure which is not useful for prevention and control of alcohol abuse among adolescents.

Which amino acids are present in the histone octamer that contribute to the stable packaging of DNA?

The lactic acid bacteria (LAB) improves nutritional quality of curd by increasing the content of -

Read the following paragraph and answer the given questions.
RNAi takes place in all eukaryotic organisms as a method of cellular defense. The source of this complementary RNA could be from an infection by viruses having RNA genomes or mobile genetic elements (transposons) that replicate via an RNA intermediate. Insulin from an animal source, though caused some patients to develop allergy or other types of reactions to the foreign protein. Insulin consists of two short polypeptide chains: chain A and chain B, that are linked together by disulphide bridges. Transgenic mice are being developed for use in testing the safety of vaccines before they are used on humans. Transgenic mice are being used to test the safety of the polio vaccine. If successful and found to be reliable, they could replace the use of monkeys to test the safety of batches of the vaccine. Specific Bt toxin genes were isolated from Bacillus thuringiensis and incorporated into the several crop plants such as cotton. The choice of genes depends upon the crop and the targeted pest, as most Bt toxins are insect-group specific. The toxin is coded by a gene cryIAc named cry. There are a number of them, for example, the proteins encoded by the genes cryIAc and cryIIAb control the cotton bollworms, that of cryIAb controls corn borer.

The Bt toxin gene cryIAb controls the:

The triple fusion in angiosperms results in the development of:

Three resistances of magnitude \(2 \Omega\), \(3 \Omega\) and \(5 \Omega\) are connected in parallel to a battery of 10 V and of negligible resistance. The potential difference across \(3 \Omega\) resistance will be:

A current change of 6 A in one coil causes the flux in the second coil of 2000 turns to change by \(12 \times 10^{-4} \text{ Wb}\) per turn. The mutual inductance of the pair of coils would be:

(B) Hybridisation using labelled VNTR probe
(C) Isolation and digestion of DNA
(D) Detection of hybridised DNA fragments by autoradiography
(E) Transferring of separated DNA fragments to synthetic membranes
