Production of a human protein in bacteria by genetic engineering is possible because
1 bacterial cell can carry out the RNA splicing reactions
2 the human chromosome can replicate in bacterial cell
3 the mechanism of gene regulation is identical in humans and bacteria
4 the genetic code is universal
Explanation:
Production of a human protein in bacteria by genetic engineering is possible because the genetic code is universal. Genetic code (Triplet) discovered by - George Gamow $$ 4^3=4 \times 4 \times 4=64 \text { codons } $$ Initiation codon $\rightarrow$ AUG 61 codons code the different Amino acid 3 codons are stopcodons/Non sense codon UAA - Ocher UAG - Amber UGA - Opel

Genetic recombination by transduction in bacteria was discovered first in this:
1 Salmonella typhimurium
2 Escherichia coli
3 Streptococcus pneumoniae
4 Agrobacterium tumifaciens
Explanation:
Transduction is a mode genetic transfer from bacteria to another through a virus. There is no direct contact between the bacterial cell. The other ways of genetic recombination in bacteria include transformation and conjugation. - In this process, bacteriophages, which infect bacteria, use host cell to multiplicate and while, when these viruses infect new bacterial cells, the bacterial genome that they carry may get inserted into the host genome transduction commonly used in genetic engineering for inserting foreign DNA into the host cell. Transduction was discovered by Zinder and Lederberg in salmonella typhimurium in 1951. - Conjugation was discover Lederberg and Tatum in 1946 in Escherichia coll. - Transformation was discovered by Frederic Griffith in 1928 in streptococcus pneumonia in 1928. - Agrobacterium tumefaciens use to transfer DNA to plant cell purposes of plant genetic engineering in $20^{\text {th }}$ century.

A technique which involves deliberate manipulation of genes within or between species
1 Gene therapy
2 Hybridoma technology
3 Tissue culture
4 Genetic engineering
Explanation:
Genetic engineering is a scientific technique that involves manipulation and organism's DNA to alter its characteristics traits or genetic makeup. This can be done by various applications, including in agricultures (creating genetically modified crops), medicine (developing gene therapy) and biotechnology. - Hybridoma technology - Hybridoma technology is a well established method to produce monoclonal antibodies (mAbs) specific to antigen's of interest. Hybridoma technology was discovered in 1975 by two scientists, Georges Kohler and Cesar Milstein. They wanted to create immortal Hybrid cells by fusing Bcells from immunized mice with their myeloma cells. - Genetherapy:- Gene therapy is a technique that modifies a person's genes to treat or cure disease gene therapies can work by several mechanism. Introducing a new or modified gene into the body to help treat a disease. - Tissue culture is technique in which cell or tissues from an organism are grown and maintained in laboratory condition. Tissue culture is widely used in various field of sciences and research, including biology, medium etc.

In cloning of cattle a fertilized egg is taken out of the mother's womb and:-
1 From this upto eight identical twins can be produced
2 The egg is divided into 4 pairs of cells which are implanted into the womb of other cows
3 In the eight cell stage, cells are separated and cultured until small embryos are formed which are implanted into the womb of other cows.
4 In the eight cell stage the individual cells are separated under electrical field for further development in culture media
Explanation:
Cloning is the process of generating a genetically identical copy of a cell or an organism. There are three types of cloning:- - Gene cloning - Therapeutic cloning - Reproductive cloning Cloning is performed in the cattle. The fertilized egg is removed from the mother's womb and then cultured in the artificial medium. The egg is allowed to grow till the eight-celled stage and then the individual cells are separated.

Agarose extracted from sea weeds finds use in :
1 Gel electrophoresis
2 Spectrophotometry
3 Tissue Culture
4 PCR/ PCR
Explanation:
Agarose is heteropolysaccharide, generally extracted from certain red sea weeds. It is frequently used in molecular biology for the separation of large molecules, especially DNA, by electrophoresis. It is a common lab technique. - Samples are loaded into well of an Agarose gel subjected to an electric field. The negative charge move towards, positive electrode - Negative charge move toward positive charge. - Shorter fragment settle down and larger size fragment floated upper side. Result Separation based on the size of fragment and charge.
