Question

In a massive, completely linear amylose chain consisting of exactly 4000 glucose monomer units, how many discrete glycosidic bonds must be hydrolytically cleaved to reduce the entire polymer length down to uniform fragments of exactly 400 units each?

Answer: A

💡 Solution & Explanation

To split a continuous linear chain of 4000 units into perfectly uniform 400-unit segments, you need exactly 10 fragments ($4000 / 400 = 10$). Creating $n$ fragments from a single linear string requires $n-1$ cuts. Therefore, $10 - 1 = 9$ cleavages are needed.
