Mutation
The long chain of amino acids is called a ______________.
Protein
This phase is where the cell grows, performs its normal functions, and prepares for DNA replication.

Protein
This phase is where the DNA is replicated in preparation for cell division.
S phase
This is the sugar found in DNA
Deoxyribose
During the formation of new strands of DNA, this enzyme adds new nucleotides to the growing strand
DNA Polymerase
The two steps of Protein Synthesis are?
Transcription and Translation
What Amino acid comes from the AUG codon
Met
: This phase is where the cell checks for any errors in the DNA before proceeding to mitosis.
G2 Phase
A nucleotide is made up of what three parts?
sugar, phosphate group and nitrogenous base

3
The phase of mitosis where the chromosomes align in the middle of the cell.
metaphase
This is small subunits that compose molecules of DNA & RNA.
Nucleotide
DNA replication is called ___________________ beucase it keeps 1/2 the old DNA and gets 1/2 the new
