DNA Modification Letter - Coggle Diagram
DNA Modification Letter
to DNA modification company
in the future
from someone dissatisfied with their modification
"you obviously don't know how it works..."
so next time they do it properly
please get rid of
__
Steps
find a platform for writing
discuss ideas
brainstorm
plan out paragraphs and sentences
Rough draft
letter format
Edit
research: What is DNA modification?
How it works?
CRISPR-Cas9
chop off DNA and reinstert
How?
target certain genes
create our own guide RNA
cas9 does the chopping
tricks repair mechanism of cell
2nd option: inserts new DNA
keeping DNA it wants
scientist introduces template
1 option: fuses
Cas9 enzyme
attacks foreign DNA
target area monitered by PAM sequences
scissors
guided by RNA
CRISPR= specialized strand of DNA
spacers and repeated sections
in bacteria
spacers from viruses
help immunity
crRNA
CRISPR RNA
RNA responds to Virus attack
makes single strand
part of CRISPR
1 spacer section
1 repeat section
There may be other ways?
selective breeding
dates back 32000 years
dogs were first
genetic engineering (modern biotechnology)
transfer DNA from one bacteria to another
first 1973
RNA Interference
removing traits
transgenics
transferring gene to another organism
mutagenesis
radiation to affect organism
further bred
causes mutation
plants
TALENS
older gene editing tool
