The molecule that carries genetic information.
DNA
A permanent change in the DNA sequence.
Mutation
This type of pathogen can only reproduce inside a host cell.
Virus
Diseases that are not caused by pathogens.
Non-infectious diseases
The group used as a comparison in an experiment.
The process that produces genetically identical daughter cells.
Mitosis
The process by which DNA produces an RNA copy.
Transcription
The white blood cells that produce antibodies.
B cells
The study of patterns, causes and effects of disease in populations.
Epidemiology
The variable changed by the researcher.
Independant variable
The stage of meiosis in which homologous chromosomes separate.
Anaphase I
The type of mutation caused by the addition or removal of nucleotides.
Frameshift
This type of immunity is produced following vaccination.
Active immunity
A change in DNA that can contribute to cancer development.
Mutation
The variable measured during an experiment.
Dependant variable
The exchange of DNA between homologous chromosomes during meiosis.
Crossing over
This process inserts foreign DNA into the genome of another organism.
Transgenesis
This process describes how pathogens are passed from one host to another.
Transmission
The loss of normal regulation of cell division leading to uncontrolled growth.
Cancer
A measure of how close repeated measurements are to each other.
Precision
This pattern of inheritance occurs when one allele is not completely dominant over another.
Incomplete dominance
The gene-editing technology derived from a bacterial defence mechanism.
CRISPR-Cas9
This evolutionary process explains the increase in antibiotic-resistant bacteria in a population.
Natural selection
The process where abnormal cells spread from their original location to other parts of the body.
Metastasis
A measure of how close results are to the true value.
