Glossary Term
Drug-, radiation-induced, or spontaneous injuries to DNA that introduce deviations from its normal double-helical conformation. These changes include structural distortions that interfere with replication and transcription, as well as point mutations that disrupt base pairs and exert damaging effects on future generations through changes in DNA sequence. If the damage is minor, it can often be repaired (DNA repair); extensive damage can induce apoptosis.
Glossary Term
Any method that extracts and purifies DNA from biological samples, which can include the proper handling of biological samples prior to nucleic acid isolation, the separation of DNA from the rest of the components in the samples, and the storage of the DNA isolates.
Glossary Term
A family of enzymes that catalyze the formation of phosphodiester bonds to repair broken strands of DNA.
Glossary Term
Enzymatic restoration of DNA structure after chemical, radiation, or spontaneous damage.
Indicators
This gene is involved in epigenetic control of gene expression.
Tests
A blood test done near the end of the first trimester of pregnancy to screen for common chromosomal defects. This test screens for blood levels of both free beta-human chorionic gonadotrophin (beta-hCG) and pregnancy-associated plasma protein A (PAPP-A) and can detect trisomies of chromosomes 21 (Down's syndrome), chromosome 18 (Edward's syndrome), and chromosome 13 (Patau's syndrome).
Glossary Term
An RNA complex consisting of two complementary base-paired strands of RNA.
Tests
Drugs are chemical substances that can change how your body and mind work. A drug test looks for signs of illegal drugs or certain prescription and/or over-the-counter (OTC) medicines that can be misused. The test is usually done with a sample of your urine (pee). Less commonly, drug testing uses a sample of your blood, saliva (spit), hair, sweat, fingernails, or breath. The purpose of a drug test is to look for drug use and misuse, which includes:
Glossary Term
The largest difference between, or ratio of, an instrument's or method's highest and lowest value in a set, such as pixel (voxel) values in an image.
Indicators
This gene plays a role in the negative regulation of transcription.

Electrolytes are minerals that have an electrical charge when they are dissolved in water or body fluids. You have electrolytes in your blood, urine, tissues, and other body fluids. They are important because they help:
