CO 1: Ability to explain
foundations of modern
biotechnology.
Definitions
• Use of biology to solve problems
• Developing Biological products useful to man
• Biotechnology” was first coined in 1917 by Karl Ereky, a
Hungarian engineer and for much of the last century; it has
been the broad term applied to the use of any living
organism for a practical purpose, anything from the
selective breeding of plants and animals to fermentation of
beer or treatment of sewage with organic materials.

Biotechnology: Is it something new ?
Prehistoric attempts by ancient ancestors to manipulate
genetic composition of useful species.
Domestication of animals and
cultivation of plants
Artificial selection of genetic
variation or selective breeding
Evidence since 8000-1000BC
Eg maize, rice, wheat, palms,
dogs, horses, camels ,oxens
Yeast for baking, wine & beers
Sumerian tablet recipe for beer 3200 BC
Ancient Egyptians diet included bread & beer
Chinese use of fermentation
using beneficial bacteria to flavor and preserve food.
Aztecs make cakes from Spirulina algae.
5000 year old bread

And the ancient Chinese first inoculated people with a weakened strain of the smallpox (variola) virus to prevent
further infection
Greek ideas of inheritance
Hippocrates (400-500BC)
Various parts of a man’s body contains “humors”
that are bearers of hereditary traits that are drawn to
contribute to the semen.
Offspring preformed as miniature, newborn which will
inherit the traits of father.
Aristotle (384-322 BC)
Male semen possess the “vital heat” which
cooks and shapes the menstrual blood
which is the “physical substance’ to give
rise to an offspring
Embryo develops as a result of shaping power of vital heat.
Dawn of modern biology
1600Theory of Epigenesis
Embryonic development
Differentiates into adult structures and organs
not present initially.
They are formed de novo.
Theory of Preformation
Sex cell contain a complete miniature adult called the
homunculus.
Its perfect in every form
Still popular in the 1700s
Dispel by embryologist Casper Wolff.
1850-1900
birth of modern genetics
Charles Darwin
Origin of species
1850
Natural selection. How does the
1859
variation that drives evolution get
transmitted? If Darwin had considered
Mendel's work he would have an available
answer. Darwin did receive Mendel's paper
but was unread (unopened).
Carl Correns, Hugo de Vries &
Tschermak
Rediscovery of Mendel’s work.
Beginning of modern genetics
1900
Gregor Mendel
Principles of Inheritance
in pea plants
1866Why was Mendel's work not appreciated b4 1900?
1900
Gregor Johann Mendel
father of classical genetics
Heinzendorf Central Europe
Augustinian monk
1856
Developed the theory of inheritance
Demonstrated with statistical data from crossing Pisum sativum
Units of inheritance exist and parents transmit these traits
to offspring in predictable pattern.
Hybridization expts thru careful observation, experimental design,
analysis and good science laid down the
principles of transmission genetics
Unappreciated , but rediscovered 1900
Experiments in plant hybridization
Pasteurization
• -1861 French chemist Louis Pasteur
develops pasteurization - preserving food by
heating it to destroy harmful microbes.
Chromosomal
theory of inheritance
Chromosomes discovered in early 20th century
Epigenetic interpretation was further established
Inherited traits are controlled by genes
They reside in chromosomes
These traits are faithfully transmitted through
gametes (reproductive cell) to future individuals
in the next generation

agent while working in Toronto.

Genetics and agriculture
GM food: increased yields, increase resistance to pest etc
super strains and special desirable qualities eg increase
protein yield, with special vitamins, or aa, reduce vulnerability
to weather conditions or pesticide.
