Clones are identical copies that describe: genes, cells, organs and organisms which carries the same genetic
information. There are two types of cloning:

Non-reproductive (or therapeutic) cloning is the process that generates identical: cells, tissues and
organs. It is…

Adsorption- enzymes bind to adsorbing agents (clay, glass beads, resin and porous carbon) by a
combination of hydrophobic interaction and ionic bonds. Gives high reaction rates as active site is
unchanged, however high leakage form as enzyme can easily…
