DNA Ligase
What happens when an enzyme changes or is damaged? (need the actual term)
It is denatured
This phase involves the formation of four haploid nuclei.
Telophase

Nitrogenous Base
List one similarity and one difference between DNA and RNA
Similarity: both contain genetic information, both located in nucleus/cytoplasm, both have A,C,G
Difference: DNA is double stranded, RNA is single stranded :: DNA has deoxyribose, RNA has ribose etc.
How does an enzyme speed up a reaction?
They decrease the activation energy.
