The National Human Genome Research Institute (NHGRI) has produced this series of fact sheets to explain complex concepts in genomics research to a non-scientific audience. Teachers, students and the general public alike will find the materials clearly written and easy to understand.

Biological Pathways
Biological Pathways Fact Sheet

A biological pathway is a series of actions among molecules in a cell that leads to a certain product or a change in the cell.

Guide to Genomics
A Brief Guide to Genomics

Genomics is the study of all of a person's genes (the genome), including interactions of those genes with each other and with the person's environment.

Chromosomes Fact Sheet

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells.

Chromosome Abnormalities
Chromosome Abnormalities Fact Sheet

Chromosome abnormalities can either be numerical or structural and usually occur when there is an error in cell division.

Cloning Fact Sheet

Cloning describes a number of different processes that can be used to produce genetically identical copies of a biological entity.

Comparative Genomics
Comparative Genomics Fact Sheet

Comparative genomics is a field of biological research in which researchers compare the complete genome sequences of different species.

Deoxyribonucleic Acid (DNA) Fact Sheet

Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique.

DNA microarray
DNA Microarray Technology Fact Sheet

A DNA microarray is a tool used to determine whether the DNA from a particular individual contains a mutation in genes.

DNA Sequencing
DNA Sequencing Fact Sheet

DNA sequencing determines the order of the four chemical building blocks - called "bases" - that make up the DNA molecule.

Epigenomics Fact Sheet

Epigenomics is a field in which researchers chart the locations and understand the functions of all the chemical tags that mark the genome.

Fluorescence In Situ Hybridization Fact Sheet

Fluorescence in situ hybridization (FISH) provides researchers with a way to visualize and map the genetic material in an individual's cell.

Genetic Mapping
Genetic Mapping Fact Sheet

Genetic mapping offers evidence that a disease transmitted from parent to child is linked to one or more genes and clues about where a gene lies on a chromosome.

Genome-Wide Association Studies Fact Sheet

Genome-wide association studies involve scanning markers across the genomes of many people to find genetic variations associated with a particular disease​.

Knockout Mice
Knockout Mice Fact Sheet

A knockout mouse is a laboratory mouse in which researchers have inactivated an existing gene by replacing it or disrupting it with an artificial piece of DNA.

Newborn Screening
Newborn Screening Fact Sheet

Newborn screening tests use a dried blood sample collected during the first week after birth to measure the presence of disease biomarkers.

Polymerase Chain Reaction (PCR) Fact Sheet

Polymerase chain reaction (PCR) is a technique used to "amplify" small segments of DNA.

The Cost of Sequencing a Human Genome | NHGRI
The Cost of Sequencing a Human Genome

Estimated cost of sequencing the human genome over time since the Human Genome Project.

DNA Sequencing Costs: Data | NHGRI
DNA Sequencing Costs: Data

Data used to estimate the cost of sequencing the human genome over time since the Human Genome Project.

Transcriptome Fact Sheet

A transcriptome is a collection of all the gene readouts present in a cell.

X chromosome
X Chromosome Fact Sheet

The X chromosome determines your sex, gives some females super color vision and lends its magic to a certain breed of cat.

Y chromosome
Y Chromosome Fact Sheet

The Y chromosome of all living men is related through a single male ancestor who lived over 100,000 years ago.

Genetics vs. Genomics Fact Sheet | NHGRI
Genetics vs. Genomics Fact Sheet

Genetics refers to the study of genes and their roles in inheritance. Genomics refers to the study of all of a person's genes (the genome).
