Study Notes
Genetic Concepts
- A plasmid is a small, self-replicating circular DNA molecule found in bacterial cells, often used as a vector in genetic engineering.
- Genotype refers to the complete set of genes an organism possesses, determining its characteristics.
- A gene is a sequence of DNA that codes for a specific protein or trait, serving as the basic unit of heredity.
Organism Characteristics
- The phenotype of an organism is the physical and behavioral expression of its genotype, resulting from the interaction of genes and environment.
- The phenotype includes characteristics such as morphology, physiology, and behavior.
Chromosomes and Heredity
- A chromosome in microbial genetics is a coiled complex of DNA and protein that carries genetic information in cells.
- The unit of heredity in genetics is the gene, which is passed from one generation to the next.
DNA and Genetic Information
- The total genetic information carried by an organism is known as its genome.
- A chromosome is a cellular structure composed of a neatly packaged DNA molecule.
- DNA contains the necessary code to make proteins and other molecules essential for life, serving as the blueprint for an organism's development and function.
