Question

answer these:

1. since glucose is an example of simple sugar, what do you think that starch is an example of?
2. there are 20 different amino acids from which proteins are built. how is this represented in the diagram?
3. how many different types of nucleotides do you see in the dna polymer?
4. what makes one nucleotide different than another?

Explanation:

1. Glucose is a simple sugar. Starch is made up of many glucose units, so it is a complex carbohydrate or a polysaccharide.
2. In a protein - related diagram, the 20 different amino acids might be represented by different shapes, colors, or symbols to show the variety of building blocks.
3. There are 4 different types of nucleotides in a DNA polymer: adenine (A), thymine (T), cytosine (C), and guanine (G).
4. Nucleotides are composed of a sugar, a phosphate group, and a nitrogen - containing base. The difference between nucleotides lies in the nitrogen - containing base.

Answer:

1. A complex carbohydrate (polysaccharide)
2. Different shapes/colors/symbols may represent different amino acids.
3. 4
4. The nitrogen - containing base.
