Chapter 11.2: DNA to Protein

Page 2: Made up of amino acids DNA codes for RNA which makes proteins

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

Protein Overview

Page 3: Made up of amino acids DNA codes for RNA which makes proteins

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

Page 4: Made up of amino acids DNA codes for RNA which makes proteins

Travels from nucleus to cytoplasm “Reads” DNA in nucleus Brings message from nucleus to ribosome

mRNA (messenger)

Page 5: Made up of amino acids DNA codes for RNA which makes proteins

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

rRNA (ribosomal)

Page 6: Made up of amino acids DNA codes for RNA which makes proteins

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

tRNA

Page 7: Made up of amino acids DNA codes for RNA which makes proteins

Going from DNA to mRNA AAATTTCCCGGG UUUAAAGGGCCC End result = One single stranded RNA

Transcription

Page 8: Made up of amino acids DNA codes for RNA which makes proteins

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

Page 9: Made up of amino acids DNA codes for RNA which makes proteins

Page 10: Made up of amino acids DNA codes for RNA which makes proteins

Going from mRNA to a protein Happens in ribosomes
