Prions are misfolded proteins with the ability to transmit their misfolded shape onto normal variants of the same protein. They characterize several fatal and transmissible neurodegenerative diseases in humans and many other animals.
Zoomed image of the surface structure of protein (clathrin). \nCan be used to cover biology booklets and presentations.
mRNA (multicoloured strand) is decoded in a ribosome to produce an aminoacid chain, that folds into a protein (red). tRNA (dark violet) molecules carry single aminoacids that are incoporated into the growing chain.
Serratia Marcescens is a rare Nosocomial Pathogen.\nThis bacterium is a gram-negative bacillus found in soil and water. it produces a red pigment at room temperature. It can cause urinary and respiratory infections, endocarditis, osteomyelitis, septicemia, wound infections, eye infections, and meningitis.
