to body cells and it is not inherited.
8. Germinal Variation pertains
to germ cells or gametes and it is inheritable.
9. Induced clones are
developed by nuclear transfer into the host cell.
10. The embryonic
stem cells can be extracted from early embryo which is developed by “invitro fertilization”.
11. The mechanism
of adult or somatic stem cell culture is similar to that of embryonic stem cell culture.
12. Antibiotics are chemical
substances derived from microbes like fungi, bacteria, etc. employed to kill
infectious germs and cure a disease.
13. Bio-chemically
significant enzymes are derived from microbes.
14.Diabetes
is treated by the biotechnologically produced insulin.
15.Bio-chips are microchips which
