What else can I help you with?
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 is meaning of bt corn?
BT corn means that the corn has been genetically modified with DNA from another organism.
How can an elisa be used in identifying bt corn?
An ELISA (enzyme-linked immunosorbent assay) can be used to identify Bt corn by detecting specific proteins produced by the Bacillus thuringiensis (Bt) bacteria, which are introduced into the corn's genetic material for pest resistance. In this assay, a sample from the corn is tested against antibodies that specifically bind to the Bt proteins. If the proteins are present, a color change indicates a positive result, confirming the presence of Bt corn. This method is quick, sensitive, and can differentiate Bt corn from non-Bt varieties.
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.
Which insects are controlled by growing Bt corn?
we cant tell you that because we dont no and what kind of question is that p.s. what is Bt corn ???
What is the relationship between European corn borer and bt corn?
The corn produces a toxin which poisons the corn borer after it consumes some of the corn.
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.
Why was Bt corn developed?
Bt-corn is a type of genetically modified organism, termed GMO. A GMO is a plant or animal that has been genetically modified through the addition of a small amount of genetic material from other organisms through molecular techniques. Currently, the GMOs on the market today have been given genetic traits to provide protection from pests, tolerance to pesticides, or improve its quality. Examples of GMO field crops include Bt-potatoes, Bt-corn, Bt-sweet corn, Roundup Ready soybeans, Roundup Ready Corn, and Liberty Link corn.
What are the genes of genetically engineered corn?
* roundup ready * Bt
Is there no risk to monarch butterflies using BT corn?
Short Answer: BT corn is a serous threat to the extinction of the Monarch. BT does not kill the Monarch, it kills the food the larva lives on, milkweed. (BT is one part of the overall habitat destruction problem; one problem of many, but maybe the one that can't be stopped before it is too late.) Explanation: The monarch butterfly is the subject of strong predation. Lots of things like to eat it or the eggs. (Not all monarchs are poison carrying.) The number of monarchs was in the hundreds of millions a few decades ago. The dramatic drop is due to habitat loss in Mexico and habitat loss over the migration region. It is in the migration region that it is getting hard for the butterflies to find the milkweed to lay their eggs on. A mere ten years ago, the vast fields across the US would have the occasional milkweed plant. Not any more. BT keeps the corn fields clean, but the effectiveness of other weed control measures has gotten better too. With Monarchs as with any member of any ecosystem, this gets complicated and it has been very unproductive to members of either side pointing individual fingers at individual factors and proclaiming them guilty. It is a system and a system that is out of balance. Traditional habitat loss, more houses and concrete and forest turned to farmland, have been progressively infringing for years as well as the problem protecting the winter site in Mexico. But, in the last few years some very negative population dynamics have been observes and extinction will occur in our lifetime. For tens of thousands of years, monarchs have been making the trek from Mexico to Canada and that is pretty nearly over with the advent of genetically modified crops.
Are any food companies using Bt corn currently?
Indirectly. Some of the large meat-production corporations are feeding Bt corn to their livestock, which are then processed into meat products for human consumption. Although it's approved for human consumption, I'm unaware of any company using Bt corn directly in a human food product.
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.
