One of my favorite parts of doing our research involves “dissecting” bags of 4 cells on Petri dishes. They each started as a single diploid cell, underwent a form of cell division called meiosis (the same process that makes sperm and egg cells), resulting in 4 haploid cells.
We use a microscope with a teeny needle controlled by a joystick to move individual cells to specific spots on a Petri dish so we can follow them individually. The different cells have different combinations of gene flavors, so we can then choose exactly which ones we need for our later experiments.
It took a while to learn how to do it correctly and quickly! Once I did, I started enjoying the process.
