In cloning of cattle a fertillized egg is taken out of the mother’s womb and
the egg is divided into 4 pairs of cells which are implanted into the womb of other cows
in the eight cell stage, cells are separated and cultured until small embryos are formed which are implanted into the womb of other cow
in the eight cell stage the individual cells are separated under electrical field for further development in culture media
in the eight cell stage the individual cells are separated under electrical field for further development in culture media
B.
in the eight cell stage, cells are separated and cultured until small embryos are formed which are implanted into the womb of other cow
In cloning of cattle a fertilized egg divides in 2, then in 4 and then in 8. This embryo is carefully removed from the womb. The embryonic cells are then separated using enzyme. Each isolated cell is kept in a nutrient medium and later implanted in the womb of a different 'host mother' cow.
