Introduction
• DNA is made of:
Nitrogenous Bases
• Cytosine=Guanine
• Adenine=Thymine

are needed to see this picture.
How DNA is copied
• mRNA, tRNA, rRNA
• codons, and amino acids
Eukaryotes
Prokaryotes
Genes
• Is a segment of DNA that codes for a
protein.
Exons
• In a gene exons are the protein coding
segments of a gene.
• Only in eukaryotes
Introns
• Introns is what gets spliced out in a
gene. (Leftovers)
Splicing
• Splicing- is the cutting out of introns.

Phylogenetic Tree
Answer
• Yes we are because we share the same
common splicing signals.
