Unit 8
  • Cloning

2
Cloning
  • In genetic engineering, cloning refers to the
    copying of DNA molecules.
  • DNA A nucleic acid that carries the genetic
    information in the cell and is capable of
    self-replication and synthesis of RNA.

    where a tense change takes place.
  • Para 1 2 act as introduction to the whole
    essay.
