5. 5. Three Types of RNA Messenger RNA (mRNA) copies DNA’s code & carries the genetic information to the ribosomesMessenger RNA (mRNA) copies DNA’s code & carries the genetic information to the ribosomes Ribosomal RNA (rRNA), along with protein, makes up the ribosomesRibosomal RNA (rRNA), along with protein, makes up the ribosomes Transfer RNA (tRNA) transfers amino acids to the ribosomes where proteins are synthesizedTransfer RNA (tRNA) transfers amino acids to the ribosomes where proteins are synthesized copyright cmassengale

6. 6 Messenger RNA Long Straight chain of Nucleotides Made in the Nucleus Copies DNA & leaves through nuclear pores Contains the Nitrogen Bases A, G, C, U ( no T ) copyright cmassengale

7. 7 Messenger RNA (mRNA) Carries the information for a specific proteinCarries the information for a specific protein Made up of 500 to 1000 nucleotides longMade up of 500 to 1000 nucleotides long Sequence of 3 bases called codonSequence of 3 bases called codon AUG – methionine or start codonAUG – methionine or start codon UAA, UAG, or UGA – stop codonsUAA, UAG, or UGA – stop codons copyright cmassengale

8. 8 Ribosomal RNA (rRNA) rRNA is a single strand 100 to 3000 nucleotides longrRNA is a single strand 100 to 3000 nucleotides long Globular in shapeGlobular in shape Made inside the nucleus of a cellMade inside the nucleus of a cell Associates with proteins to form ribosomesAssociates with proteins to form ribosomes Site of protein SynthesisSite of protein Synthesis copyright cmassengale

9. 9 The Genetic Code A codon designates an amino acid An amino acid may have more than one codon There are 20 amino acids, but 64 possible codons Some codons tell the ribosome to stop translating copyright cmassengale

10. 10 The Genetic Code Use the code by reading from the center to the outside Example: AUG codes for Methionine copyright cmassengale

11. 11 Name the Amino Acids GGG? UCA? CAU? GCA? AAA? copyright cmassengale

12. 12 Remember the Complementary Bases On DNA: A-T C-G On RNA: A-U C-G copyright cmassengale

13. 13 Transfer RNA (tRNA) Clover-leaf shape Single stranded molecule with attachment site at one end for an amino acid Opposite end has three nucleotide bases called the anticodon copyright cmassengale

14. 14 Transfer RNA amino acid attachment site UAC anticodon copyright cmassengale

15. 15 Codons and Anticodons The 3 bases of an anticodon are complementary to the 3 bases of a codon Example: Codon ACU Anticodon UGA UGA ACU copyright cmassengale
