Due to inhibition of polygalacturonase enzyme which degrades pectin. Transgenic variety of Tomato - Flavr Savr. Scientists produced rice capable of synthesizing β - carotene. By inserting two genes from daffodil and one gene from a bacterial species into the rice. Rice is a staple food in many countries. These crystals contain a toxic insecticidal protein. Bt forms protein crystals during a particular phase of their growth. Some strains of Bt produce proteins that kill certain insects such as lepidopterans, coleopterans, and dipterans. The source of this complementary RNA could be from infection by viruses having RNA genomes or mobile genetic elements (transposons) that replicate via an RNA intermediate. This method involves silencing of a specific mRNA due to a complementary dsRNA molecule that binds to and prevents translation of the mRNA (silencing). RNAi takes place in all eukaryotic organisms as a method of cellular defense. A novel strategy was adopted to prevent this infestation which was based on the process of RNA interference (RNAi). A nematode Meloidogyne incognita infects the roots of tobacco plants and causes a great reduction in yield. The first genetically modified plant was produced in 1982, an antibiotic-resistant tobacco plant. It is a plant that has a novel combination of genetic material obtained through biotechnology that adds a new quality to the parent crop like herbicide-tolerance. Transgenic plants can be made by introducing foreign DNA into a variety of different tissues. 
Transgenic means that one or more DNA sequences from another r species have been introduced by artificial means.GM plants can reduce reliance on chemical pesticides (pest-resistance crops).
This crop is known as genetically modified crops (GM crops).
A transgenic crop is a crop whose genes have been altered by manipulation. Electric shock is when an electric current is passed through the membrane, and thus the membrane becomes permeable and foreign DNA enters the cell.īelow is the diagrammatic representation of the somatic cell nuclear transfer technique. Microinjection is a technique in which DNA is introduced inside cell cytoplasm via a micropipette. A liposome-mediated transfer is when DNA is enclosed in a lipid bilayer structure and introduced in the lipid bilayer of the membrane as it allows the liposome containing foreign DNA to enter inside a cell. After the gestation period was over dolly was born. The egg is introduced to the surrogate mother. 
The DNA obtained from the mammary gland of another sheep was injected into the enucleated egg. In this technique, the egg from a donor sheep is obtained, and its nucleus was removed (enucleated). Dolly was made using the somatic cell nuclear transfer technique. The correct answer is the Somatic cell nuclear transfer technique.
