Prions – Definition, Structure, Replication, Function, Disease

Prions Disease: Definition, Structure, Prevention, Control, Treatment, Transmission.

What are Prions? Definition of Prion A prion is an infectious, misfolded protein that causes neurodegenerative diseases by inducing abnormal folding of normal cellular proteins, leading to the accumulation of these misfolded proteins in the brain. Unlike other infectious agents, prions lack nucleic acids and propagate their abnormal structure through direct protein-protein interactions. Characteristics of … Read more

Animal Cell Labeled Diagram, Structure, Types, Functions

Animal cell are considered to be the fundamental living species belonging to the kingdom Animalia. They are eukaryotic cells which means they possess an actual nucleus as well as organelles, which are special structures which perform various functions. Animal cells don’t have specific organelles for plants, such as cell walls that support the plant cell or the chloroplasts, an organelle that is responsible for photosynthesis.

Rothera’s test – Definition, Principle, Procedure, Result

results of Rothera’s test

Acetoacetic acid and acetone react with an alkaline solution of sodium nitroprusside to form a purple-colored complex. This method can detect above 1-5 mg/dl of acetoacetic acid and 10-20 mg/dl of acetone. Beta-hydroxybutyrate is not detected.
