Production of transgenic animals notes

Production of transgenic animals notes. Transgenic animals can be used to produce valuable products. Es cells are obtained from the inner cell mass of a blastocyst. Following natural gestation and birth offspring are subject to tissue biopsy and blood sampling. Theoretically all living beings can be genetically manipulated. The first transgenic animal was produced in 1983 when genes for human growth hormone were introduced into mice. Transgenic animals are just one in a series of developments in the area of biotechnology. The transgenic animals are created because of the benefits they provide to the man. Usually ear tissue and blood are screened by polymerase chain reaction and or southern analysis for the presence of the transgene. After injecting the dna the embryo is implanted into the uterus of receptive females. Transgenic animals transgenic animals are animals that have been cloned. There have been numerous reports and applications of transgenic plants in agriculture mainly to benefit the producer. Transgenic animals are those that have been genetically modified. Applications of transgenic animals. The production of transgenic animals has focused mainly on producing models e g the mouse for basic and medical research.

The transgenic animals are created because of the benefits they provide to the man. There are several types of transgenic animals like transgenic sheep birds chickens pigs insects etc. Sheep goats pigs cows rabbits rats mice fish insects parasites and even humans have previously been used in this modification process. Transgenic animals can be created by manipulating embryonic stem cells. Animals with manipulated genetic material carrying recombinant dna are known as transgenic animals. Transgene is incorporated into the es cell by microinjection by a retro virus by electroporation transgenic stem cells are grown in vitro. Transgenic animals for the production of therapeutic and diagnostic proteins are produced by transferring fertilized transgene carrying embryos to recipient animals. Let us discuss a few of them here. The major successes have been achieved in the transfer of. Then they are inserted into a blastocyst and implanted into a host s uterus to grow normally. However the realization of genetically engineered livestock has been much slower.
