1. RNA and Protein Synthesis

2. I. RNA Formed from nucleotides Single stranded
Uracil instead of thymine
Sugar  Ribose
Copies the DNA info for protein synthesis

3. 3 Types of RNA: rRNA (ribosomal): help make up ribosome
mRNA (messenger): carries the DNA info from nucleus to ribosome
tRNA (transfer): brings amino acids to ribosomes to build proteins

5. RNA vs DNA

7. II. Protein Synthesis A. Transcription:
The DNA code is transcribed (copied) into mRNA in the nucleus

8. B. mRNA moves into the cytoplasm, attaching to a ribosome

9. Translation: Each codon of mRNA selects a tRNA with a specific amino acid
Ribosome reads the mRNA and joins amino acids to form a protein
(polypeptide chain)

10. E. After delivering its amino acid, tRNA picks up another amino acid

12. From Gene to
Protein
