Which process can be used to rapidly produce a group of genetically identical plants from the cells of a single plant? (1) screening (2) karyo- typing (3) gene splicing (4) cloning

Direct DNA transfer method(s) used for plant genetic engineering is(are)(A) microparticle bombardment(B) electroporation(C) polyethylene glycol treatment(D) Agrobacterium-mediated transformation

In which region of plants can cells differentiate to produce all types of tissue?LeavesMeristemRootsShoots2Plants can be cloned from small groups of cells in tissue culture. Why is auxin added to the tissue culture?To kill the cellsTo give the cells resistance to pesticidesTo stimulate the cells to growTo ensure the cells do not become infected3Which of the following is an advantage of producing new plants by cloning?Can be used to cultivate plants that are difficult to growAll of theseCan be used to help preserve endangered speciesCan help growers cultivate plants with the best characteristics4To develop animal tissue cultures, cells are separated from sample tissue and then bathed in a liquid within a culture vessel. What is added to the liquid?DrugsNutrients and growth factorsCompost and auxinViruses5Which of the following is not a use for animal tissue cultures?Testing drugsMaking drugsStudying cancer cellsGrowing skin grafts

Which two applications of gene cloning involve transgenic organisms?

Tissue culture is another way of producing a lot of plants.Cells or a small piece of tissue are removed from a parent plant, treated with hormones and kept in sterile, nutrient rich conditions.Each cluster of cells will grow into a whole new plant, however, it is fairly expensive and must be done in a lab.Suggest an advantage of this technique over taking cuttings.It is a faster way of producing new plants.Many more offsprings can be made from one parent plant.It is more expensive to take cuttings.It is easier to produce plants by tissue culture.
