Study Notes
Anatomical Terminology
- Anatomical terminology is a standard system of words and phrases used to describe the human body and its parts in a precise and consistent way, enabling effective communication among healthcare professionals.
Karyotype
- A karyotype is the complete set of chromosomes in a cell, typically depicted as a photograph or diagram showing the arrangement of chromosomes in a cell nucleus.
Cell Division
- Mitosis is the process of cell division that results in two daughter cells with the same number of chromosomes as the parent cell.
- Meiosis is the process of cell division that results in four daughter cells with half the number of chromosomes as the parent cell, occurring in reproductive cells.
DNA Replication
- The main function of DNA replication is to create an exact copy of the entire genome before cell division, ensuring that each new cell receives a complete set of genetic instructions.
Mendelian Inheritance
- The different types of Mendelian inheritance patterns include autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive, and Y-linked inheritance.
Gene as Unit of Inheritance
- A gene is the basic unit of inheritance, defined as a segment of DNA that carries information necessary for the development and function of an organism.
Mitosis vs Meiosis
- The main difference between mitosis and meiosis is the number of daughter cells produced and the number of chromosomes in each daughter cell, with mitosis producing two diploid daughter cells and meiosis producing four haploid daughter cells.
DNA Structure
- The chemical structure of DNA is a double helix, consisting of two complementary strands of nucleotides that twist together, with sugar molecules and phosphate groups forming the backbone and nitrogenous bases projecting inward.
High Fidelity Copy
- The term for the high fidelity copy of DNA during replication is a replica, which is an exact duplicate of the original DNA molecule.
Autosomal Recessive Inheritance
- Autosomal recessive inheritance is a pattern of inheritance where a person must inherit two copies of a mutated gene (one from each parent) to express the trait, with carriers being unaffected but able to pass the mutated gene to offspring.
