Nuclear transfer

<p>Nuclear transfer is a form of <a href="/facts/Cloning/Vb6SM4c7">cloning</a>.  The step involves removing the <a href="/facts/DNA/nB89Iauz">DNA</a> from an <a href="/facts/Oocyte/aYrWtc3n">oocyte</a> (unfertilised egg), and injecting the <a href="/facts/Cell_nucleus/D7sFRa3c">nucleus</a> which contains the DNA to be cloned. In rare instances, the newly constructed cell will divide normally, replicating the new DNA while remaining in a <a href="/facts/Pluripotent/81323LbR">pluripotent</a> state.  If the cloned cells are placed in the uterus of a <a href="/facts/Female_mammal/hk4wM9y1">female mammal</a>, a cloned organism develops to term in rare instances. This is how <a href="/facts/Dolly_the_Sheep/P1kNJQeY">Dolly the Sheep</a> and many <a href="/facts/List_of_animals_that_have_been_cloned/Jf37KrNv">other species</a> were cloned. Cows are commonly cloned to select those that have the best milk production. On 24 January 2018, two <a href="/facts/Monkey/ARjd5RRr">monkey</a> <a href="/facts/Clone_(cell_biology)/h8rRU6Y9">clones</a> were reported to have been created with the technique for the first time.
</p><p>Despite this, the low efficiency of the technique has prompted some researchers, notably <a href="/facts/Ian_Wilmut/QluqI3WQ">Ian Wilmut</a>, creator of <a href="/facts/Dolly_(sheep)/P1kNJQeY">Dolly</a> the cloned sheep, to abandon it.
