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.
