Question

How are selective breeding, cloning, and genetic engineering similar? They are all controlled by nature. They are all controlled by humans. They all begin with the use of udder cells. They all involve the use of enzymes that cut DNA.

Answer 1

Answer:They are all controlled by the human beings.

Explanation:

The selective breeding, cloning and genetic engineering are some of the techniques which is induced by the human efforts.

In case of selective breeding the male and female species having the selective characters are mated with each other so that the offspring produced  has the desired characters. It neither requires any enzyme nor uses udder cells.

In case of genetic engineering, the gene of interest is inserted in the bacterial species by the help of vector so that when the bacterial species amplify the gene of interest. This is how the desired products are produced by bacterial species. Example: Insulin production.

Cloning can be defined as another technique made by human beings in which the genetically identical species is made naturally or artificially for the benefit of the mankind.
