8 What is the correct order of the procedure of Somatic Cell Nuclear Transfer?

I. An electric current is delivered to stimulate the egg to divide
II. The unfertilized egg is removed from a female adult and its haploid nucleus is removed
III. The enucleated egg cell is fused with the nucleus from the adult donor
III. The embryo is implanted into the uterus of a surrogate
  • A.   II  → III  → I  → IV
  • B.   I  → III  → II  → IV
  • C.   I  → II  → III  → IV
  • D.   II  → I  → III  → IV

  • B.   Organisms that reproduce sexually can produce clones
  • C.   Organisms that reproduce asexually can produce clones
  • D.   Cloning multicellular organisms requires the use of differentiated cells
10. A gene can be isolated and amplified in order to genetically modify a specific vector. Which enzymes are involved in the process of gene transfer to bacteria using plasmids?
