5.19 Describe the stages in the production of cloned mammals involving the introduction of a diploid nucleus from a mature cell into an enucleated egg cell, illustrated by Dolly the sheep

·         Dolly is the clone and it’s identical.

·         This is clone by removing the cell (diploid cell). Nucleus contains all genetic information.

·         Different animals treated to egg, tends to divide. Take the nucleus so, its enucleated.

·         We take the cells and fuse them together and by mitosis we get the blastula (embryonic sheep we start).

·         Then embryo put in the serrated mother and gives a birth sheep which is young sheep ‘Dolly’. Pair is clone even though their age is different.
