Study Notes
Biology Fundamentals
- Evolution has transformed life on Earth.
Definition of Biology
- Biology is the study of life.
Genetic Code
- Genetic information is coded in living things through DNA.
Cell Biology
- The study of cell structure and function is called cell biology or cytology.
Characteristics of Life
- The properties of life include obtaining and using energy, interacting with the environment, regulating themselves, growing, developing, and reproducing.
Plant Structure
- According to Schleiden, the fundamental unit of plant structure is the cell.
Cell Theory
- Matthias Jakob Schleiden and Theodor Schwann proposed the idea that all living organisms are made of cells.
DNA Structure
- James Watson and Francis Crick discovered the double helix structure of DNA in 1953.
Evolution
- Charles Darwin published 'On the Origin of Species by Means of Natural Selection' in 1859.
Central Dogma
- The central dogma of molecular biology states that genetic information flows from DNA to RNA to proteins.
Characteristics of Life
- Homeostasis, which involves obtaining and using energy, interacting with the environment, regulating themselves, growing, developing, and reproducing, is a fundamental concept in biology.
Cell Biology
- Cytology is the discipline that focuses on the structure and function of cells.
Paleontology
- Paleontology is the scientific field concerned with the study of ancient life forms and their interactions with the environment.
Heredity
- Heredity refers to the transmission of genetic information from one generation to the next.
Biochemistry
- Biochemistry is the area of biology that focuses on the study of chemical processes within and relating to living organisms.
Cell Theory
- According to the cell theory, cells are not created spontaneously from non-living matter.
One Gene - One Protein Hypothesis
- Beadle and Tatum proposed in 1940 that one gene is responsible for the production of one enzyme, which has been updated to 'one gene - one protein' or 'one gene - one polypeptide' in modern times.
Domains of Life
- There are three domains of life: Archaea, Bacteria, and Eukarya; viruses are not included in this classification system.
Evolution
- Charles Darwin published 'On the Origin of Species by Means of Natural Selection' in 1859.
Cell Biology
- The study of cell structure and function is called cell biology or cytology.
