Cloning is the creation of an organism that is an exact genetic copy of another. There are different types of cloning. A basic understanding of the different types of cloning is key to taking an informed stance on current public policy issues and making the best possible personal decisions.
The following 3 types of cloning technologies (1) recombinant DNA technology or DNA cloning, (2) reproductive cloning, and (3) therapeutic cloning.
What is a Clone ?
As per biology, a clone is a cell or an organism that is genetically identical to another cell or organism. Many simple organisms such as bacteria reproduce themselves by copying their DNA and splitting in half.
The two bacteria that result from this form of asexual reproduction are genetically similar, they are clones of each other. In contrast, during the process of sexual reproduction, the nucleus of a sperm cell, which carries the father's DNA, fuses with the nucleus of the egg cell, which contains the mother's DNA. The resulting offspring carry genetic material from both parents and are not identical to either parent.
The verb "to clone" refers to the process of creating cloned cells or organisms. The process differs, depending on the kinds of cells used in the cloning procedure and the desired result. Usually, when scientists clone an animal, they take the nucleus of a cell -- which contains chromosomes made of deoxyribonucleic acid (DNA) and proteins -- and place it into an egg cell (also called an oocyte) from which the nucleus has been removed. The egg cell then divides to produce an embryo that develops into an animal, if the procedures work as planned.
wow. thats wierd.
