The desired genes and the vectors are cut by the same restriction enzymes to obtain the complementary sticky notes, thus making the work of the ligases easy to bind the desired gene to the vector. In this step, the recombinant DNA is introduced into a recipient host cell. Draw a stepwise mechanism for the following reaction: atp → adp. Thus the recombinant DNA has to be introduced into the host. Recombinant DNA technology is widely used in Agriculture to produce genetically-modified organisms such as Flavr Savr tomatoes, golden rice rich in proteins, and Bt-cotton to protect the plant against ball worms and a lot more. This ion acts as a very good leaving group which leaves to form a carbocation.

Draw A Stepwise Mechanism For The Following Reaction: 2C→4A+2B

The second method is another example in which an intermediate sulfonate ester confers halogen-like reactivity on an alcohol. The technology used for producing artificial DNA through the combination of different genetic materials (DNA) from different sources is referred to as Recombinant DNA Technology. 3° alcohols: 25°– 80°C. The lone pair of electrons on oxygen atom makes the –OH group weakly basic. Explain the roles of the following: (a) Restriction Enzymes. There are multiple steps, tools and other specific procedures followed in the recombinant DNA technology, which is used for producing artificial DNA to generate the desired product. A technique mainly used to change the phenotype of an organism (host) when a genetically altered vector is introduced and integrated into the genome of the organism. The first and the initial step in Recombinant DNA technology is to isolate the desired DNA in its pure form i. e. free from other macromolecules. Recombinant DNA Technology- Tools, Process, and Applications. Yeast cells, viruses, and Plasmids are the most commonly used vectors. The relative reactivity of alcohols in dehydration reactions is ranked as follows: Methanol < primary < secondary < tertiary. Draw the mechanism of its formation. Gene Therapy – It is used as an attempt to correct the gene defects which give rise to heredity diseases. Also Refer: Genetically Modified Organisms (GMO).

The major product of this mechanism would be the more highly substituted alkene, or the product formed from the red arrows. This gives rise to sticky ends in the sequence. However, the general idea behind each dehydration reaction is that the –OH group in the alcohol donates two electrons to H+ from the acid reagent, forming an alkyloxonium ion. Assume no rearrangement for the first two product mechanisms. It is a process to amplify a single copy of DNA into thousands to millions of copies once the proper gene of interest has been cut using restriction enzymes. Once the recombinant DNA is inserted into the host cell, it gets multiplied and is expressed in the form of the manufactured protein under optimal conditions. Plasmids are circular DNA molecules that are introduced from bacteria. There are a number of ways in which these recombinant DNAs are inserted into the host, namely – microinjection, biolistics or gene gun, alternate cooling and heating, use of calcium ions, etc. This molecule is made to replicate within a living cell, for instance, a bacterium. Note how the carbocation after the rearrangement is resonance stabilized by the oxygen. The vectors – help in carrying and integrating the desired gene. Draw a stepwise mechanism for the following reaction: mg s +. They scrutinize the length of DNA and make the cut at the specific site called the restriction site.

Draw A Stepwise Mechanism For The Following Reaction: Atp → Adp

Plasmids and bacteriophages are the most common vectors in recombinant DNA technology that are used as they have a very high copy number. In the dehydration of this diol the resulting product is a ketone. Insertion of Recombinant DNA Into Host. Dehydration of Alcohols to Yield Alkenes. Listed below are the applications of gene cloning: - Gene Cloning plays an important role in the medicinal field. Note: While the mechanism is instructive for the first part of the this answer. Draw a stepwise mechanism for the following reaction: 2c→4a+2b. Let's understand each step more in detail. This process is termed as Transformation. It is used in gene therapy where a faulty gene is replaced by the insertion of a healthy gene.

It carries genes, which provide the host cell with beneficial properties such as mating ability, and drug resistance. Also Read: R-Factor. Frequently Asked Questions. Gene therapy in diseases like cancer, SCID etc. The hydroxyl oxygen donates two electrons to a proton from sulfuric acid (H2SO4), forming an alkyloxonium ion. The dehydration reaction of alcohols to generate alkene proceeds by heating the alcohols in the presence of a strong acid, such as sulfuric or phosphoric acid, at high temperatures. The required range of reaction temperature decreases with increasing substitution of the hydroxy-containing carbon: - 1° alcohols: 170° - 180°C. Notice in the mechanism below that the alkene formed depends on which proton is abstracted: the red arrows show formation of the more substituted 2-butene, while the blue arrows show formation of the less substituted 1-butene. In this step of Ligation, the joining of the two pieces – a cut fragment of DNA and the vector together with the help of the enzyme DNA ligase. Process of Recombinant DNA Technology. Production of transgenic plants with improved qualities like insect and drought resistance and nutritional enrichment. The vectors are made up of an origin of replication- This is a sequence of nucleotides from where the replication starts, a selectable marker – constitute genes which show resistance to certain antibiotics like ampicillin; and cloning sites – the sites recognized by the restriction enzymes where desired DNAs are inserted. Then the conjugate base, HSO4 –, reacts with one of the adjacent (beta) hydrogen atoms while the alkyloxonium ion leaves in a concerted process, forming a double bond. For the production of vaccines like the hepatitis B vaccine.

Draw A Stepwise Mechanism For The Following Reaction: Mg S +

Additinally, trans alkenes are more stable than cis alkenes and are also the major product formed. The Endonucleases cut within the DNA strand whereas the Exonucleases remove the nucleotides from the ends of the strands. Oxygen can donate two electrons to an electron-deficient proton. Therapeutic protein production like insulin. DNA technology is also used to detect the presence of HIV in a person. These reactions are called 'restriction enzyme digestions'. The enzymes which include the restriction enzymes help to cut, the polymerases- help to synthesize and the ligases- help to bind. If there was a rearrangement, draw the expected major product. The minor product being the same product as the one formed from the red arrows. Primary alcohols undergo bimolecular elimination (E2 mechanism) while secondary and tertiary alcohols undergo unimolecular elimination (E1 mechanism). 2° alcohols: 100°– 140 °C.

Different types of alcohols may dehydrate through a slightly different mechanism pathway.
