What is the process of somatic cell nuclear transfer (SCNT)?

Back

SCNT is a cloning technique where the nucleus of a somatic cell is transferred into an egg cell from which the nucleus has been removed.

Front

What ethical concerns are associated with cloning?

Back

Ethical concerns include the potential for genetic manipulation, animal welfare, and the implications of cloning in humans.

Front

What is genetic engineering?

Back

Genetic engineering is the direct manipulation of an organism's genes using biotechnology.
