True or false:Human tissues can be cloned in a Petri dish.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Cloning using somatic cell nuclear transfer (SCNT) [ 1]. This procedure starts with the removal of the chromosomes from an egg to create an enucleated egg. The chromosomes are replaced with a nucleus taken from a somatic (body) cell of the individual or embryo to be cloned.

Detailed explanation-2: -1 No one has ever cloned a human being, though scientists have cloned animals other than Dolly, including dogs, pigs, cows, horses and cats. Part of the reason is that cloning can introduce profound genetic errors, which can result in early and painful death.

Detailed explanation-3: -The genes of an individual, the genome, can be cloned, but the individual itself cannot be cloned, as it will be made clear below. Cloning genes or, more generally, cloning DNA segments is routinely done in many genetics and pharmaceutical laboratories throughout the world (12, 31).
