Phylogenetic
Scientist use a phylogenetic tree to track the evolutionary history of a species.
They only allow certain substances to go through.
Dna is double stranded
rna is single stranded
sugar in dna is deoxyribose
sugar in rna is ribose
nitrogenous bases in dna are adenine thymine guanine and cytosine whereas rna has uracil instead of cytosine
dna stays in the nucleus
rna leaves the nucleus
