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.
