Answer:
Beta-amyloid is a metabolic waste product that’s found in the fluid between brain cells (neurons). A build-up of beta amyloid is linked to impaired brain function and Alzheimer’s disease. In Alzheimer’s disease, beta-amyloid clumps together to form amyloid plaques, which hinder communication between neurons. Impaired sleep has been associated with Alzheimer’s disease. Lack of sleep has been shown to elevate brain beta-amyloid levels in mice
Answer

Answer:
IV, VI, III, I
Explanation:
Translation is the process of synthesis of protein from with the help of messenger RNA (mRNA).
The process of translation include initiation, elongation and termination.
- Initiation: In this step mRNA binds to ribososomes and tRNA, carrying start codon or methionine binds to mRNA.
- Elongation: In this step, the tRNA molecules carrying several amino acid bind to mRNA based on the sequence of mRNA codon and then moves (translocates) to the next mRNA codon which leads to amino acid chain.
- Termination: At the end, when a stop codon (UGA) identified, polypeptide is released.
So, the correct chronological order is IV, VI, III, I.
