understanding dna Flashcards
what is the backbone of DNA made of?
phosphate.
what are the rungs of DNA made of?
Nitrogenous base.
what is the building block (monomer) of DNA? (polymer)
Nucleotide
what are three components of a nucleotide?
Phosphate, deoxyribose, nitrogenous base
what are three functions of the DNA molecule?
Mutates, copies, contains genes
why does DNA mutate?
Because it creates variety and leads to evolution
Why does DNA copy?
Because it needs to make copies of itself
why does DNA contain genes?
by acting as a template for RNA protein production.
What are functions of deoxyribose?
forms the backbone of DNA, helps DNA remain intact, and binds to nitrogenous bases
what are functions of phosphate?
Forming the backbone of nucleic acid, creating a high energy bond and storing and releasing energy
what are functions of nitrogenous bases?
base pairing, genetic information structure, and hydrogen bonds
what are functions of nitrogenous bases?
base pairing, genetic information structure, and hydrogen bonds
