Front

Microevolution

Back

Changes in a population’s genetic structure.

Front

Mismatch repair

Back

A form of DNA repair in which non-complementary nucleotides are recognized, excised, and replaced with correct nucleotides.

Front

Lagging strand

Back

During replication of the 3' to 5' strand, the strand that is replicated in short fragments and away from the replication fork.

Front

Deoxyribose

Back

A five-carbon sugar molecule with a hydrogen atom rather than a hydroxyl group in the 2' position; the sugar component of DNA nucleotides.

Front

Translation

Back

The process by which ribosomes synthesize proteins using mRNA as a template.

Front

Gene flow

Back

The transfer of genetic variation from one population to another.

Front

Natural selection

Back

The process whereby organisms better adapted to their environment tend to survive and produce more offspring.

Front

Genetic drift

Back

A mechanism of evolution that refers to random changes in the frequency of alleles in a population.

Front

Homologous chromosomes

Back

Chromosomes that are similar in shape, size, and genetic content.

Front

Phenotype

Back

The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences.
