Reproductive technologies focus on the transfer of genetic information - HSC - SSCE Biology - Question 12 - 2004 - Paper 1

The process that only involves the transfer of the nucleus is Cloning. In cloning, specifically in techniques such as somatic cell nuclear transfer (SCNT), the nucleus from a donor cell is transferred into an egg cell that has had its nucleus removed. This is the crucial step that differentiates cloning, as it directly utilizes the nucleus of a single cell to create a new organism, in contrast to other options like transgenesis, artificial pollination, and artificial insemination, which involve other mechanisms of genetic transfer.
