Study Notes
Methods of Diagnosis
- Molecular diagnosis uses characteristics to determine the cause of disease.
Genotypic Diagnosis
- The greatest advantage of genotypic diagnosis is that it allows for precise identification of genetic mutations.
- The disadvantage of genotypic diagnosis is that it can be complex and time-consuming.
Module Overview
- The main focus of this module is on the relationship between genetics and disease.
DNA and Proteins
- DNA contains the instructions for making proteins, which perform various functions in the body.
Genetics History
- Gregor Mendel is known as the Father of Genetics.
- Gregor Mendel discovered the laws of inheritance through his pea plant observations.
Human Chromosomes
- Humans have 23 pairs of chromosomes, for a total of 46 chromosomes.
- Sex chromosomes (X and Y) are responsible for determining the sex of an individual.
Genetics Fundamentals
- A gene is a unit of heredity that carries information from one generation to the next.
