Study Notes
- Genetics is the study of heredity and how traits are passed down from generation to generation.
- Gregor Mendel discovered the role of genes in inheritance through his hybridization studies of pea plants in the mid-19th century.
- Humans have between 20,000 and 25,000 genes that make up their genome.
- Genetic information is stored in the form of DNA in every cell's nucleus.
- DNA is made up of nucleotides and bases thymine, adenine, guanine, and cytosine.
- Genes provide the coding for all information about a person's inherited traits.
- The human genome project was launched at the turn of the 21st century to decode human DNA.
- Genetics research has led to opportunities in medicine such as genetic testing and gene manipulation.
- There are ethical questions and risks associated with these opportunities.
- Finding answers to these ethical questions may be the next stage of our understanding of genetics.
