Chapter 1 ( Timeline of Biotech) Flashcards
When Fermentation First developed?
4000 BC
When plant breeding first developed?
3000 BC
What was developed during 1700 BC?
Beer
When Antiobiotics from moldy tokwa developed?
500 BC
Where antibiotics from modly tokwa developed ?
China
What is the usage of moldy tokwa in China?
Treat boils
Soy sauce of China is Made From?
Soy bean
Commercially improved corn release.
1890’s
In 1929 ,how biotech being modified?
Fermentation produce antibiotics ( penicillin) and bio conversion producing enzymes.
Plants tissue culture.
1940-1960
Discovery of the DNA structure.
1953
How biotech modified in 1970?
Recombinant DNA technology
Rec Health Products and industrials produced in cell cultures.
1980’s
PCR development.
1983
Development of Zinc Finger Nuclease
1985
Mammalian Cell culture and Microbial Cell Culture.
1880’s
Genetically Modified crops developed and Cloning of dolly the sheep ( the first modified animal)
1990’s
In 1999,how biotech modified?
The first chromosome sequence.
First human chromosome mapped.
2000’s
First human gene therapy trial.
2001
First induced pluripotent stems cell.
2006
One of the “cellsthat are self-replicating, are derived from human embryos or human fetal tissue, and are known to develop intocellsand tissues of the three primary germ layers.
Pluripotent stem cells.
Genome editing tools.
2010
Restriction enzymes that can be engineered to cut specific sequences of DNA. They are made by fusing a TAL effector DNA-binding domain to a DNA cleavage domain (a nuclease which cuts DNA strands).
TALENS ( Transcription Activator Like Effector Nuclease)
TALENS discovered.
2011
Adapted from a naturally occurring genome editing system in bacteria. The bacteria capture snippets of DNA from invading viruses and use them to create DNA segments
CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)
CRISPR developed.
2012
First GM Animals (Salmon) approved for commerced.
2015
Human trials for CRISPR
2018
