Flashcards

What are two light-independent DNA repair systems?

Base excision repair and nucleotide excision repair are two types of DNA repair that don't require light.

How many amino acids are commonly found in proteins?

Proteins are made up of 20 different amino acids.

What is the generalized structure of a carbohydrate?

The general structure of a carbohydrate can be represented as (CH2O)n, where n is the number of carbon atoms.

What is the general term for a large molecule made up of many similar subunits?

A polymer is a large molecule composed of many repeating smaller subunits called monomers.
