Today we started class with a simple goal: draw a picture of one of your human cells. Human beings are made up of trillions of cells. They’re microscopic. So how hard could it be? Actually… pretty hard.
Students had to include a strip of their DNA, color-coded to match yesterday’s genetic code. Then they had to add in the other 45 chromosomes as well. They also had to include a ribosome, some RNA, and a ribosome building a protein. And that’s not even every organelle. And in reality, each chromosome is millions of base-pairs long. So much for realism.
