Homework Answers
Creutzfeldt Jakob disease is caused by prions. Prion is a type of protein that can trigger normal proteins in the brain to fold abnormally. Prion diseases can affect both humans and animals and are sometimes spread to humans by infected meat products.

Distinguish between the different levels of protein structure, including primary, secondary, tertiary, and Question Prions are a type of protein implicated in bovine spongiform encephalopathy (BSE), also known as "mad cow disease," and related pathologies found in sheep (scrappie) and humans (Creutzfeldt-Jakob disease). The disease occurs when sections of an otherwise healthy protein misfold from alpha-helices to beta-pleated sheets, forming tightly packed sections of beta-pleated sheets that are difficult to break down. The disease propagates because the misfolded prions induce...

The human eye disease retinitis pigmentosa is caused by a loss of function mutation (rp) in the gene PRPF31. The disease is expressed when combined with wildtype allele 1 (rp+1) in a heterozygote, but not expressed when combined with wildtype allele 2 (rp+2) in a heterozygote. When comparing the number PRPF31 mRNA transcripts in the eyes of rp/rp+1 and rp/rp+2 individuals, researchers have found higher number of functional PRPF31 mRNAs in the eyes of rp/rp+2 individuals. This is an example...
