Answer:
D) (CH2O)n, where n can be 3-7
Explanation:
Monosaccharides are the simplest carbohydrate that has a formula of (CH2O)n where n at least have to be 3. Since its the simplest form, monosaccharides can't be broken down into smaller carbohydrates.
If the number of n is less than 3, it won't become monosaccharides. A molecule with CH2O formula is called an aldehyde. That is why option C is wrong. The answer will be option D
The answer is 12 since there are 4 nucleotides
