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.
