In vivo experiments are done using ____
living organisms (“in life”)
Molecular genetics is the science of _____
solving biological questions using DNA, RNA, and proteins isolated from organisms (in vitro)
Molecular genetics began in ____ with _____
1970 with the discovery of restriction enzymes
In vitro experiments are done ____

organelle DNA (euk. only)
total RNA
mRNA
Methods used for nucleic acid isolation (2)
DIY (cheaper)
Kit (faster)
DIY isolation of nucleic acid
uses reagents present in lab (ex. NaOH)
Genomic DNA isolation kit uses _____
blood samples
Genomic DNA isolation Kit method
- Release DNA (Enzymatic digestion)
- Bind DNA (Add ethanol and spin)
- Wash column (Wash and spin twice)
- Elute DNA (Spin 1 minute)
Which is easier to isolate? RNA or DNA? Why?
DNA (more stable)
Harder to isolate RNA because it is unstable temporary molecule)
After nucleic acid isolation, DNA is treated with ____
enzymes from Biotech companies
