What is transgenic fish and its application?
A transgenic fish is one that contains genes from another species. A transgenic fish is an improved variety of fish provided with one or more desirable foreign gene for the purpose of enhancing fish quality, growth, resistance and productivity.
Which is the main objective in development of transgenic fish?
Transgenic fish have been used to study developmental regulation of genes, improve cold tolerance, increase growth rate, and improve feed utilization. Fast growing transgenic coho salmon, medaka, rainbow trout and tilapia containing novel growth hormone genes reached sexual maturity sooner than unmodified counterparts.
What is transgenic fish production?
Transgenesis is the introduction of exogenous genetic material (DNA) into a host genome, resulting in its stable maintenance, transmission and expression. The first successes in producing genetically modified transgenic fish occurred in 1984 and 1985 with rainbow trout and goldfish.
What was the first transgenic fish?
During the FDA-funded study, William Muir and Richard Howard found that laboratory fish called the Japanese medaka (Oryzias latipes) that were genetically modified to produce human growth hormone matured faster and carried more eggs than non-GM relatives.
Which is the first transgenic fish that was used as food?
Salmon
Long-awaited decision authorizes a genetically engineered animal to grace US dinner tables for the first time. A fast-growing salmon has become the first genetically engineered animal to be approved for human consumption in the United States.
Which of the following properties are observed in transgenic fish?
Solution. Both Increased cold tolerance and Improved growth.
What means transgenic?
Transgenic refers to an organism or cell whose genome has been altered by the introduction of one or more foreign DNA sequences from another species by artificial means. Transgenic organisms are generated in the laboratory for research purposes.
Which of the following genes have been introduced into the transgenic fish?
1 Answer. Transgenic fish are transfected with E. coli hygromycin resistance gene, growth hormone and chicken crystalline protein.
Which of the gene have been introduced into the transgenic fish?
Abstract. The human growth hormone gene has been used to produce the first batch of transgenic fish and to establish a transgenic fish model The transgenic fish with functional human growth hormone gene grew up to 4.6 times as fast as the control.
What is an example of transgenic organism?
Transgenic organisms have also been developed for commercial purposes. Perhaps the most famous examples are food crops like soy and corn that have been genetically modified for pest and herbicide resistance. These crops are widely known as “GMOs” (genetically modified organisms).
