Different forms of a gene for a particular trait

The process where cells become specialized to specific organs and tissues while developing in the uterus

Consisting of the heart, blood and blood vessels, it transports substances within animals

Coding Region/ Coding DNA

The specific part of a gene's DNA or RNA sequence that provides instructions for building a protein

Passive movement of materials across a membrane from HIGH concentration to LOW concentration, requiring NO ENERGY

A trait that will appear in offspring if ONE of the parents contributes it

A biological protein catalyst necessary to speed up chemical reactions such as synthesizing and breaking down molecules.

The study of changes in gene expression not caused by changes in the DNA sequence

When a gene is actively working and it is seen in an organism. It can be influenced by the environment (Himalayan rabbit color, suntans)

A distinct section of DNA that codes for a protein

An organism's genetic makeup which causes its phenotype

An enzyme that breaks down the sugar lactose into glucose and galactose. It's essential for digesting milk and milk products, as it allows the body to absorb the simple sugars produced from lactose.

A disaccharide sugar primarily found in the milk of mammals. It's composed of two monosaccharides, glucose and galactose, linked together. Lactose is broken down by the enzyme lactase into glucose and galactose, allowing the body to absorb and utilize the

The ability to digest lactose, the sugar in milk, into adulthood

When chemical tags called methyl groups attach to a particular location within DNA where they turn a gene on or off, thereby regulating the production of proteins that the gene encodes

Non-Coding Region/ Non-Coding DNA

DNA that does not code for proteins but may have regulatory roles

Outward physical appearance of an organism caused by its genotype

The likelihood of an event occurring; used in genetics

A trait not expressed in an organism because it is masked by a dominant trait

Genes that control the expression of other genes, acting as switches that turn genes on and off

Any factor that influences the survival and reproduction of individuals within a population, leading to changes in the frequency of certain traits over time

The process where DNA is copied into RNA

The process where RNA is used to build a protein
