Study Notes
Cell Biology Fundamentals
- Cell biology studies the fundamental chemical components, reactions, and structures that govern cells
- It also examines how cells acquire and use nutrients/energy
- Further, it explores the macromolecular assemblies and interactions that allow cells to perform essential tasks like storing, processing, and propagating genetic information
- These tasks also include molecular transport and communication with the outside environment
Cell Theory
- Cells are the basic functional units of life
- All living organisms are made up of cells
Reasons for Studying Cells
- Diseases stem from cellular-level disturbances
- Cellular processes underpin human health and illness
- Over two hundred different cell types exist in the human body
Common Features of All Cells
- Cells are complex and well organized
- Cells possess a genetic program
- Cells can reproduce themselves
- Cells are biochemical factories that utilize energy
- Cells participate in mechanical processes
- Cells react to stimuli
- Cells are capable of self-regulation
- Evolution originates at the cellular and molecular levels
Biological Themes
- Biology involves counterpoints between diverse occurrences and fundamental consistencies
- The complexity of individual organisms coexists with fundamental mechanisms that unify living systems
Model Eukaryotes
- "Model organisms" provide crucial insights, such as sequenced genomes, that enable researchers to study genetic modification and track gene expression in multiple cells at the same time
- These organisms include:
- Yeast (S. cerevisiae, S. pombe)
- Arabidopsis thaliana (Common Thale Cress)
- C. elegans (a nematode worm)
- Drosophila melanogaster (the fruit fly)
- Mouse (Mus musculus)
