What does it mean when a plant is a BT-plant?
BT-plant means plant having BT-gene like BT-cotton. These are transgenic plants developed by genetic engineering.
How bt corn is made?
Bt corn is made by introducing vector plasmids into agrobacterium by electroporation. Electroporation is the creation of transporent pores in the membrane of a cell, through the application of a high-voltage electrical pulse.
How could a person find out if there is a fault on their BT line?
The easiest way to determine if there is a fault on the BT line is to try using the line. If there is an interferrence free connection then the line will be fine. BT's website also enables you to enter your telephone number and it will tell you if there are any reported issues with your line.
When one gene expresses itself over another the former gene is said to be the DNA?
The gene that expresses itself over the other is Dominant. The former gene is recessive.
Explain 2 ways technology is used in the field of genetics?
1. Medical Applications: Medical transcription software has slowly replaced the need for manual transcription services that could take up to a week to turnaround a dictation; today’s innovative software and technologies are designed to automate the dictation-to-reporting process so that the final product can be retrieved within 24-48 hours. 2. Human Gene Therapy: Gene therapy is the medical treatment of a disease by repairing or replacing defective genes or introducing therapeutic genes to fight the disease. Over the past ten years, certain autoimmune diseases and heart disease have been treated with gene therapy. 3. Pharmaceutical Products: Different types of medicine can be created and used to fight diseases that are caused by genetic defects and problems in the DNA 4. Forensic Evidence: DNA evidence can be used to identify a perpetrator - even decades after the commission of a crime. 5. Environmental Clean Up: The new genetic techniques now allow us to establish more precisely the diversity of microorganisms and identify those critical to maintaining or restoring the function and integrity of large and small ecosystems; this knowledge also can be useful in monitoring and predicting environmental change. 6. Agricultural Application: The cultivation of recombinant DNA-modified crops, first introduced in 1995, now exceeds 100 million acres, and such crops are grown by 7 million farmers in 18 countries, their total cultivation remains but a small fraction of what is possible. 7. Pharm Animals: It involves genetic modification of an animal embryo's genetic makeup, or genome. Just after fertilization, "pharmers" insert into the embryo a human gene that codes for a particular protein -- usually one that's produced naturally in humans, but that's lacking in people who have certain diseases. They attach that DNA code with a gene that codes for a sugar found in mammalian milk, insuring that the therapeutic protein will be expressed only in the animals' milk or eggs. -GTC's ATryn contains the human protein antithrombin, which helps prevent blood clots that could lead to a stroke or heart attack 8. Plant Engineering: Plants can be genetically engineered to produce their own Bt. Genetic (recombinant DNA) engineering is the modification of DNA molecules to produce changes in plants, animals or other organisms. Bacillus thuringiensis, commonly known as Bt, is a bacterium that occurs naturally in the soil and can be used to kill insects. Steps: First, scientists identify a strain of Bt that kills the targeted insect. Then they isolate the gene that produces the lethal protein. That gene is removed from the Bt bacterium, and a gene conferring resistance to a chemical (usually antibiotic or herbicide) is attached that will prove useful in a later step. The Bt gene with the resistance gene attached is inserted into plant cells. At this point, scientists must determine which plant cells have successfully received the Bt gene and are now transformed. Any plant cell that has the Bt gene must also have the resistance gene that was attached to it. Researchers grow the plant cells in the presence of the antibiotic or herbicide and select the plant cells that are unaffected by it. These genetically transformed plant cells are then grown into whole plants by a process called tissue culture. The modified plants produce the same lethal Bt protein produced by Bt bacteria because the plants now have the same gene. Research to transfer insect resistance genes from Bt to crop plants is well under way. Corn, cotton and potatoes are three of the many commercial crops targeted for Bt insect resistance.
What does the Bt gene produce and how does it affect insects that eat plants that express the gene?
The Bt gene produces a soil-inhabiting bacteria. This bacteria is known to be made into insecticides and kills insects that eat plants with the Bt genes.
What does it mean when a plant is a BT-plant?
BT-plant means plant having BT-gene like BT-cotton. These are transgenic plants developed by genetic engineering.
Bt corn is a genetically modified crop that contains a gene from another species Which characteristic does this gene give the plant?
The gene inserted into Bt corn is from a bacterium called Bacillus thuringiensis (Bt) which produces a protein toxic to insect pests. This gene helps the plant generate a toxin that targets specific insects such as corn borers.
How was Bt corn probably created?
To make Bt corn, a gene is taken from a bacterium called Bacillus thuringiensis. The gene produces a protein that kills corn borer larvae, so growers can use Bt corn as an alternative to spraying insecticides.
What are the possible gametesafter meiosis for the genotype BbTt?
The possible gametes after meiosis for the genotype BbTt are BT, Bt, bT, and bt. The two alleles for each gene (B/b and T/t) will assort independently during meiosis, leading to four possible combinations of alleles in the gametes.
Why the the cry gene of Bt cotton is not harmful to humans?
The Cry gene in Bt cotton encodes a protein that is toxic to certain insect pests like caterpillars and not harmful to humans because the protein specifically targets the insect digestive system, which is different from humans. Additionally, the protein is broken down during digestion, so it does not accumulate in the human body. Extensive studies have confirmed the safety of Bt crops for human consumption.
Is it mandatory to be a BT broadband or BT mobile customer to get free BT WI-fi?
Yes you have to be a BT broadband or BT mobile customer.
What happens to a pest that eats a plant with the Bt gene in its cells?
Death or nothing describes what happens to a pest that eats a plant with the Bt gene in its cells. Bacillus thuringensis has 96 genes for toxins that punch fatal holes in insect larvae guts, with different toxin proteins matching different species-specific types of receptors. It works, for instance, with the gene in corn matching the receptor in European corn borers, but not matching those of beneficial insects or of cotton, potato and other pests.
What is the print reading of abbreviation of bathtub?
BT is Bathtub BT is also Bolt in some cases
Where could a person buy BT routers?
One can get a BT router from BT. If one subscribes to BT Broadband one will usually get a BT router as part of the package. A BT router can also be bought on eBay.
Is bt a unit of measure?
I have seen units/bt where bt stands for bottle
What is the market cap for BT Group plc BT?
