Study Notes

The Chromosomal Basis of Heredity

Genes are packaged with proteins in the form of chromatin.
Genes are organized into chromosomes.
Chromosomes play a role in the transmission of genetic information.
Mitosis and meiosis are both important in cell division.
A cell is the basic unit of life and the smallest functional and structural unit of living organisms.
The history of the cell dates back to the discovery of the compound microscope in 1595.
In 1655, Hooke described "cells" in cork.
In 1838, Schleiden and Schwann proposed the cell theory.
In 1858, Rudolf Virchow concluded that all cells come from pre-existing cells.
The cell theory states that all living organisms are made of one or many cells.
Cells are the basic structural units of all organisms.
Prokaryotic cells have a specific structure, including chromosomes.
Chromosomes are thread-like structures derived from the Greek words "chroma" meaning color and "soma" meaning body.
