What is 46
Name the phases of Mitosis in order from first to last.
What is PMATC
Regions of DNA which do not code for proteins?
What is introns
This enzyme fills in errors and empty spaces where nitrogenous bases should be.
What is DNA Polymerase III
A section of DNA that codes for a protein is called?
What is a gene
This phase of mitosis is where the cell spends most of its time growing and preparing itself.
What is interphase?
Regions of DNA which code for a proteins is called?
What is an exon.
DNA polymerase builds DNA molecules in reverse of each other. This is called being:
What is semiconservative
structures that DNA wraps around that helps give Chromosomes their structure and shape?
What are histones.
Chromosomes that are elongated and have the histones very far apart from each other are in what form?
What is chromatin

What is Chromatin
In prophase this structure surrounding chromosomes dissolves away and allows chromosomes to freely move inside the nucleus.
What is the nuclear envelope?
