CryIAbis introduced in a plant to prevent infestation by corn borer. (a) What is the resultant plant referred as? (b) Summarize the action of the gene introduce?
class 12th CBSE Biology sample paper
Answers
a)The resultant will refer as Bt corn
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.
b) Cry I Ab/ Bt toxin gene codes for crystal protein; the Bt toxin protein exists as an inactive protein, but once an insect ingests it, it gets converted into an active form due to the alkaline pH of the gut which solubilizes the crystal. The activated toxin binds to the surface of mid gut and creates pores that cause swelling, lysis and eventually death of the insect.
a). Bt corn
b). Bt toxin encode for crystal protein which can kill the corn borer.
Explanation:
a). Bt corn is produced by the insertion of CrylAbis in the plant genome so as to make it resistant to the infestation of corn borer. The Bt corn is a genetically modified crop because a genetic material of another organism is inserted into it.
b). The gene introduce produces protein called as crystal protein which is toxic for the corn borer hence, helps preventing the growth and abundance of the corn borer population.
