Mitosis vs. Meiosis

Mitosis is a type of cell division that produces two identical daughter cells. It's used for growth and repair. Meiosis is a type of cell division that produces four genetically distinct daughter cells. It's used for sexual reproduction.

Autosomal Dominant Disorders

Autosomal dominant disorders require one copy of the mutated gene to be present. Examples include Huntington's disease.

Autosomal Recessive Disorders

Autosomal recessive disorders require two copies of the mutated gene to be present. Examples include cystic fibrosis.

X-linked Recessive Disorders

X-linked recessive disorders affect males more often than females and are passed from mother to son. Examples include hemophilia.

Innate vs. Adaptive Immunity

Innate immunity is a non-specific, immediate defense against pathogens. Adaptive immunity is a specific, slower defense that remembers pathogens.

PAMPs vs. DAMPs

PAMPs are pathogen-associated molecular patterns, found on bacteria, viruses, and fungi. DAMPs are damage-associated molecular patterns, released from damaged cells.

Chain of Infection

The chain of infection describes the steps involved in the spread of an infection. It includes the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host.
