Cloning has been seen in the news and as a major topic of de

Solution

Cloning is a mechanism of producing a number of identical copies. The individual obtained after cloning is called clone. A cloned individual will have no parents biologically. Cloning of DNA is called molecular cloning, while cloning of animal is called animal cloning. Cloning of a DNA involves four steps

Fragmentation where the strands of DNA

Ligation where the DNA fragments are joined together

Transfection, inserting the DNA into the cell

Screening were the cells which are successfully transfected cells are selected.

Dolly, a sheep was the first animal to be cloned successfully.

Advantages of Cloning include

Animals of selected traits can be bred for example, sheep which yield more wool.

In agriculture cloning is of great advantage to get higher yields by cloning two species of plants. The methodology was employed for mangoes, rubber, banana, orchids

Cloning is utilized in organ and tissue harvesting

Cloning is efficient in solving fertility problems, where a couple cannot produce fertile offspring cloning helps.

Couples who have lost their child, cloning would help them in have their child back.

Disadvantages of Cloning include

Cloning may lead to mutation where extreme abnormalities in the cloned species may occur.

Due to cloning there are chances of new diseases.

People have a believe that cloning is like we are playing with god and hurts the ethical issues of some people.

Insufficient research in the field is a obstacle and the success rate is less.
