Extraction of DNA from White Onion
High schoolers conduct lab test with minced onion to determine where chromosonal DNA is located within the cell, and whether or not it can be extracted.
Curated OER
ISOLATION OF DNA FROM ONION
Pupils perform a lab in which they extract DNA from onion cells. Students break through the cell and nuclear membranes and then break down the protein that the DNA is wrapped around.
Curated OER
DNA Isolation
Students use scientific methods to investigate the concept of DNA. They observe the DNA of human cheek cells. This is done with the use of a lab experience. Students record their observations and reflect upon on how each organism is...
Curated OER
Evolution Lab
Students examine the pattern of natural variation in a society. They examine Darwin's theory of evolution and analyze data. They use computer programs to graphically display the variation in organisms.
