Binary Fission steps - -Initiated when proteins attach DNA to plasma membrane -Begins along ORI region -Newly synthesized DNA also anchored to membrane -Cell elongates until ~2 times its original size and two has two chromosomes on opposite ends of the cell -Cell splits in two Quiescent stem cells, function - Permanently arrested in G0 phase. In adults: can replace non-reproducing specialized cells) ex adult skeletal muscle/myofiber) Steps of quiescent stem cell to myofiber - -Activate...

Abiogenesis - The process of life originating from inanimate (lifeless) matter by natural causes All forms of life grouped into these 3 domains - Archaea Bacteria Eukarya Amyloplasts - A type of leucoplast Colorless plastids that store starch, a product of photosynthesis Anaphase - Sister chromatids separate and move to opposite spindle poles Movement continues until the separated chromatids are now called daughter chromosomes Anchoring belts - form belts that run entirely around cells ...
