What else can I help you with?
An Infectious particle made up of protein rather then DNA or RNA?
A prion is an infectious particle composed solely of protein that can cause abnormal folding of other proteins in the brain, leading to neurodegenerative diseases like mad cow disease. Prions are known for their unique ability to self-replicate by inducing normal host proteins to adopt the misfolded prion form.
What is the name of the agent that contains no nucleic acid?
Prions are agents that contain no nucleic acid. They are infectious proteins that can cause misfolding of normal proteins in the brain, leading to neurodegenerative diseases such as mad cow disease and Creutzfeldt-Jakob disease.
What is the causes mad cow disease?
infectious proteins called prions
Infectious particle made of protein?
Prions are infectious proteins. Examples are the well known "mad cow disease" or bovine spongiform encephalopathy (BSE; affects cattle), scrapie (affects sheep), Creutzfeldt-Jacob disease, Kuru, Gerstmann-Sträussler-Scheinker syndrome, and Fatal familial insomnia. Variant Creutzfeldt-Jakob disease (vCJD) is the disease that occurs in humans when BSE proteins from cattle enter humans.
Do prions contain DNA or RNA?
Prions are an infectious particle made of protein. They do not contain DNA or RNA.
What body systems uses antibodies proteins and specialized cells to defend the body from infectious diseases?
The immune system uses antibodies, proteins, and specialized cells to defend the body from infectious diseases. This includes systems like the lymphatic system, which contains white blood cells that identify and neutralize invaders, and the lymph nodes which produce and store infection-fighting cells.
What one of these is an infectious protein?
They are called Prion. This is the definition I fount at wordnetweb.princeton.edu/perl/webwn: "an infectious protein particle similar to a virus but lacking nucleic acid; thought to be the agent responsible for scrapie and other degenerative diseases of the nervous system".
What molecule contains all the information a cell needs to make proteins?
The DNA contains the 'blueprints' for proteins.
What do the antibody proteins do?
They bind to antigens, which can be either proteins, carbohydrates, or proteins decorated with attached carbohydrates. This allows the immune system to recognize infectious organisms and parasites so it can prepare to fight them.
What instructions are building proteins?
DNA contains the instructions to make proteins.
Which class of molecule contains the amino group NH2?
proteins !
What is a small ball like particle in the cytoplasm that build proteins?
Ribosomes
