Students have had an
exciting week while learning about DNA and Genetics. We are beginning to
understand how tiny these stings of molecules really are, yet so detailed in
their nature. We also discovered that DNA unites all living organisms!
Earlier
this week, students started to build their own strand of DNA (a gene).
All the strands of DNA will be complete by Monday so we can combine and
assemble the 7th grade DNA ladder.
On Wednesday,
students partook in a DNA isolation and extraction lab where they were able to
look at actual DNA from a split pea. We broke the cell wall, nucleus and
other proteins away from the DNA in order to see the tiny strands clearly in
test tubes. I was really impressed with how well the students did in this
lab. They were really able to see quite a bit of DNA.
