Disorder characterised by slow and inefficient formation of blood clots leading to prolonged bleeding and spontaneous internal bleeding.
Term given to a cell with only one set of chromosomes, for example, the sex cells (sperm and egg).
A condition when the heart can no longer pump enough blood around the body. It usually occurs when the heart muscle has become too weak or stiff to work efficiently.
Key enzyme involved in DNA replication, it is responsible for ‘unzipping’ the double helix structure by breaking the hydrogen bonds between bases on opposite strands of the DNA molecule.
A type of chemical used to kill unwanted plants.
Also known as iron overload disease, it is an inherited disorder in which iron accumulates in the blood because too much is absorbed by the intestines.
A rare condition, but the most common inherited syndrome that predisposes people to early-onset colorectal cancer.
An organism that has both male and female reproductive organs.
An individual who carries two different alleles for a particular gene.
A protein found in the nucleus of eukaryotic cells, which is involved in packaging DNA into structural units called nucleosomes.
An individual who carries two of the same alleles for a certain gene.
The body’s chemical messengers, carried in the bloodstream to tissues or organs. Important in many processes in the body, from reproduction to development.
A retrovirus that infects humans and attacks the immune system. Left untreated, HIV can lead to acquired immunodeficiency syndrome (AIDS).
A group of viruses that infect your skin and the moist membranes lining your body, such as your mouth, throat and genitals. Cause abnormal tissue growth and genital warts.
A progressive neurodegenerative disorder, caused by a mutation in a single gene called huntingtin (HD), which usually develops in middle to late adult life. The mutation results in neuronal cell death in select areas of the brain and causes uncontrollable muscle spasms.
Your body’s defence system that recognises and defends the body against pathogens such as bacteria and viruses.
The ability of an organism to resist a particular infection or disease due to having the specific antibodies or white blood cells needed to defend against it.
Reproduction resulting from the mating of a pair of individuals that are genetically closely related. Can lead to reduced fitness in a population.
The time it takes between becoming infected with a disease and beginning to show symptoms.
A type of stem cell generated from an adult cell that has been reprogrammed to act like an embryonic stem cell.
Disease caused by a microorganism such as a virus, bacterium or parasite. They can be spread from one person to another.
An immune reaction that results in localised redness, warmth and swelling. It generally occurs in response to an infection, irritation or injury.
The inability to sleep.
A hormone produced by the pancreas that regulates the amount of the sugar glucose in the blood. A lack of insulin or an inability to respond to insulin causes diabetes.
Part of a gene that is not used to make protein and is cut out from the RNA between transcription and translation.
An electrically charged particle formed when an atom loses or gains electrons.
An image of all the chromosomes from an individual cell. Used to check for large-scale chromosome abnormalities.
One thousand bases, or pairs of bases (1000 b or 1000 bp). In molecular biology, commonly used to describe the length of a DNA/RNA molecule.
Often done in model organisms, knockouts are when specific genes in an organism’s genome are inactivated. This allows scientists to understand more about the role of certain genes and what happens if they are absent.
The lagging strand is a single DNA strand that, during DNA replication, is replicated in the 5' - 3' direction (opposite direction to the replication fork). DNA is added to the lagging strand in discontinuous chunks called ‘okazaki fragments’.
