Which of the following animal is mostly used in genetics experiments?
1 Butterfly
2 Fruitfly
3 Housefly
4 Dragonfly
Explanation:
Fruitfly (Drosophila Melanogaster) is the mostly used in genetic experiment. Fruitfly typically used in genetic engineering because it is an animal species that is easy to care for. It has four pairs of chromosomes, it breeds quickly and lays many eggs. As polytene chromosomes, sex determination and sex linked inheritances have been studied in fruitfly.

Construction of a recombinant DNA involves:
1 cleaving and rejoining DNA segments with endonuclease alone
2 cleaving DNA segments with endonuclease and rejoining them with ligase
3 cleaving DNA segments with ligase and rejoining them with endonuclease
4 cleaving and rejoining DNA segments with ligase alone
Explanation:
The contraction of recombinant DNA involves cleaving DNA segments with endonuclease and rejoining them with ligase. Recombinant DNA technology involves using enzymes and various laboratory techniques to manipulate and isolate DNA fragments of interest.

Which one is used in the production of insulin by genetic engineering?
1 Eschereria coli
2 Mycobacterium
3 Both $[a]$ and $[b]$
4 None of these
Explanation:
E.coli is used in the production of insulin by genetic engineering. Insulin is a small protein produced by the pancreas in vertebrates and controls the body uptake of glucose from the blood. Obtaining this insulin is an expensive procedure and obviously insulin from other animals is not as effective as the human insulin may be because of the small size and its value, the production of Human insulin by recombinant DNA technology was early goal of pharmaceutical industry.

What is the first step in the Southern blot technique?
1 Denaturation of DNA on the gel for hybridization with specific probe.
2 Production of a group of genetically identical cells
3 Digestion of DNA by restriction enzyme
4 Denaturation of DNA from a nucleated cell such as the one from the scene of crime
Explanation:
First step in southern blot technique is the digestion of DNA by restriction enzymes. Restriction fragment preparation, separation by electrophoresis, Denaturation of DNA by chemical treatment, single standard DNA are transferred on to special paper or nylon use of radioactive probe, which is called Autoradiography.

Various enzymes and hormones can be produced on large scale by employing the recombinant :
1 DNA technique
2 RNA technique
3 viral technique
4 bacterial technique
Explanation:
The first step in development of recombinant DNA technology was the characterization of restriction endonucleases. The process involves combining the DNA of different organism. The process depends on the ability to cut and re-join DNA molecules at points which are identified by specific sequence of nucleotide bases called restriction sites.
