Study Notes

Cell Biology

Cells are the fundamental units of life, the basic structural and functional units of all known living organisms.
Cells are classified into two main types: prokaryotic and eukaryotic.
Prokaryotic cells—lack a membrane-bound nucleus and other membrane-bound organelles. They are typically smaller than eukaryotic cells.
Eukaryotic cells—have a membrane-bound nucleus and other membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus. They are more complex and larger than prokaryotic cells.
Cell membranes are selectively permeable, regulating the passage of substances into and out of the cell. This is critical for maintaining homeostasis.
Cellular respiration is the process by which cells convert glucose into energy in the form of ATP.
Photosynthesis is the process by which plants and other autotrophs convert light energy into chemical energy in the form of glucose.
Cell division is essential for growth, repair, and reproduction in living organisms. There are various processes including mitosis (somatic cells) and meiosis (gamete production).

Genetics

Genetics is the branch of biology concerned with heredity and variation in organisms.
Genes are segments of DNA that contain the instructions for making specific proteins.
DNA (deoxyribonucleic acid) is a double-stranded helix that carries genetic information. It's the primary carrier of gentic information.
RNA (ribonucleic acid) is a single-stranded molecule that plays a crucial role in protein synthesis.
The central dogma of molecular biology describes the process of information flow from DNA to RNA to protein.
Different forms of a gene are called alleles. This leads to variations in traits.
Meiosis is the process by which sex cells (gametes) are produced. It results in haploid cells containing half the number of chromosomes as the parent cell.
Mendelian genetics describes the principles of heredity discovered by Gregor Mendel. It focuses on traits determined by single genes.
Non-Mendelian inheritance patterns exist beyond the basic principles of simple inheritance, such as incomplete dominance, codominance, and polygenic inheritance.
Chromosomes are thread-like structures in the nucleus that carry genes. Chromosomes are made up of tightly coiled DNA.
Mutations are changes in the DNA sequence.
Genetic variations are the differences in genes or other DNA sequences among individuals within a species or population. These are fundamental to evolution and adaptation.
Gene expression is the process by which DNA information is used to synthesize proteins. This often involves multiple steps and regulation points.
The genetic code is the set of rules governing how codons in mRNA are translated into amino acids during protein synthesis.

Biology

Biology is the scientific study of life and living organisms.
Key concepts such as evolution, adaptation, biodiversity, and the interconnectedness of life are central to biology.
Biological systems are organized at different levels of complexity, spanning from molecules forming cells, then tissues, organs and organ systems. This can lead to entire organ systems in multicellular organisms like mammals.
The mechanisms of inheritance, as explored by genetics, underpin evolution by natural selection.
Homeostasis is the ability of organisms to maintain a stable internal environment in response to external changes. This is crucial for the proper functioning of cells and organisms.
Ecology is the study of the relationships between organisms and their environment. This includes the interactions between organisms in ecological communities (e.g., competition, predation, symbiosis) and organisms and their surrounding environment
