Study Notes
Taxonomy and Classification
- Taxonomy: The study of the general principles involved in scientific classification, crucial for organizing biological diversity.
- Classification: The method of assigning objects or organisms to categories based on shared characteristics, essential for understanding relationships.
Domains of Life
- Domain: A taxonomic category that ranks above kingdoms; the three primary domains are Archaea, Bacteria, and Eukarya.
- Eubacteria: A domain comprised of unicellular prokaryotes, distinguishing them from the Archaea domain.
- Archaea: Another domain of unicellular prokaryotes, characterized by distinct genetic and biochemical features that set them apart from Eubacteria.
- Eukaryotae: This domain includes organisms composed of eukaryotic cells, which are complex cells with membrane-bound organelles.
Nucleic Acids
- DNA (Deoxyribonucleic Acid): A double-stranded, helical molecule that serves as the genetic blueprint for organisms, carrying instructions for protein synthesis and inheritance.
- RNA (Ribonucleic Acid): A single-stranded nucleic acid composed of ribose sugar and nitrogenous bases (adenine, cytosine, guanine, uracil), playing a vital role in translating genetic information into proteins.
Genes and Proteins
- Gene: A segment of DNA that encodes the information necessary to produce a specific protein.
- Enzyme: A type of protein that acts as a biological catalyst, accelerating chemical reactions within cells.
- Protein: A complex three-dimensional polymer made from amino acid monomers that perform various functions in the body.
Cellular Functions
- Cytochrome c: A crucial protein involved in the process of cellular respiration, present in nearly all living organisms, highlighting its fundamental role in energy production.
