Notes on Chromosomes, Mitosis, & Meiosis What is a chromosome? Chromosomes = condensed DNA, same material, coiled more tightly into individual bundles.
1 Gene Expression Every cell has the same DNA Yet, each cell is different, specialized Differences due to gene expression Which genes are turned on
MITOSIS and the CELL CYCLE. Cell Cycle vs. Mitosis Cell cycle= life cycle of a cell; growth, division, etc. Mitosis= one step of the cell cycle; division.
The Cell Cycle and Mitosis. What is Mitosis? Mitosis is the process by which eukaryotic cells divide. Prokaryotes divide through a simpler process called.
Chromosomes are the structure in which DNA is packaged. Centromere is the region where sister chromatid are bound together. Gene is a segment of.
