200
A nitrogenous base that pairs with cytosine by a hydrogen bond on the opposing side of the double helix.
What is guanine
200
DNA is packed into chromosomes

200
Sticks out sideways from the nucleotide chain
What is a nitrogenous base

The theory that adenine and thymine, as well as, cytosine and guanine exist in equal amounts in a DNA molecule
What is Chargaff's rule
300
The monomer of nucleic acids.
What is a nucleotide
300
These cells have a single, circular DNA molecule
What is prokaryotic cell
300
Type of bond that holds together nitrogenous bases on opposing sides of the DNA molecule
What is a hydrogen bond
300
Each strand of DNA holds the genetic code in opposite directions. Thus, DNA can be described as...
What is antiparallel
400
An enzyme that copies and proof reads the genetic code during replication by adding nucleotides
What is DNA polymerase
400
Replication starts in a single spot and proceeds in two directions until the entire molecule is copied
What is prokaryotic cell
400
Type of bond that holds together the backbone of DNA
What is a covalent bond

What is 35%
500
An enzyme that begins the replication process by unwinding the DNA
