2. There are approximately 6 million people living with Alzheimer's in America. It is thought that Alzheimer's can be caused by incorrectly formed proteins. Use what we know about proteins/DNA to explain how mutations and changes in DNA can lead to Alzheirmer's Can Alzheirmers be passed down through genetics? How so? Must answer in approximately 5-6 sentences in order to receive full credit.​

Inheritance. Early-onset familial Alzheimer disease is inherited in an autosomal dominant pattern , which means one copy of an altered gene in each cell is sufficient to cause the disorder. In most cases, an affected person inherits the altered gene from one affected parent.

Explanation: Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills, and, eventually, the ability to carry out the simplest tasks. In most people with Alzheimer’s, symptoms first appear in their mid-60s. Estimates vary, but experts suggest that more than 5.5 million Americans, most of them age 65 or older, may have dementia caused by Alzheimer’s.

b - the respond is innate and varies over time.
