Made up of amino acids DNA codes for RNA which makes proteins
Protein Overview

Double stranded vs. Single stranded Deoxyribose sugar vs Ribose sugar Thymine vs Uracil A now bonds with U NOT with T in RNA
DNA vs RNA

Travels from nucleus to cytoplasm “Reads” DNA in nucleus Brings message from nucleus to ribosome
mRNA (messenger)

Found in ribosomes Reads the message mRNA brought Tells tRNA what to do “Boss” of the RNA
rRNA (ribosomal)

Found in cytoplasm Listens to rRNA Brings correct amino acid to the ribosomes Allows a protein to be built “Workers” of RNA
tRNA

We have 20 amino acids in us Every 3 nucleotides (letters) codes for 1
amino acid Called a codon EX: UUU = phenylalanine 64 possible codons Some codons code instructions, not amino
acids UAA = stop AUG = start
Amino Acids

Going from mRNA to a protein Happens in ribosomes
Translation
