clearly defined nucleus, nucleolus and chromatin visible
Interphase - G1
growing to normal size
Interphase - S
Synthesis of DNA, replication
Interphase - G2
growing to 2x normal size, prepare for cell division (mitosis)
Prophase, Metaphase, Anaphase, Telophase. Nucleus divides.
Nucleolus disappears and chromosomes appear. Centrioles migrate to opposite poles. Spindle forms.
Spindle attach to chromosomes. Chromosomes line up in the middle of the cell.
Chromosomes separate and move to opposite poles. Furrow formation, beginning of cytokinesis.
Produces two identical daughter cells. Opposite of prophase.
What limits cell size?
DNA overload, exchanging materials, ratio of surface area to volume.
Bacterial chromosomes are made of
a single circular strand
bacteria divide by a process called
