RiboNucleic Acid -RNA

1. RiboNucleic Acid-RNA RNA is responsible for the movement of genetic information from the DNA in the cell nucleus to the site of protein synthesis in the cytoplasm.

2. RNA vs. DNA • RNA's sugar molecule is ribose instead of the deoxyribose sugar in DNA.

3. RNA vs. DNA • RNA's sugar molecule is ribose instead of the deoxyribose sugar in DNA. • RNA is single stranded, not double stranded like DNA.

4. RNA vs. DNA • RNA's sugar molecule is ribose instead of the deoxyribose sugar in DNA. • RNA is single stranded, not double stranded like DNA. • RNA has Uracil not Thymine

5. RNA vs. DNA • RNA's sugar molecule is ribose instead of the deoxyribose sugar in DNA. • RNA is single stranded, not double stranded like DNA. • RNA has Uracil not Thymine • RNA is synthesized by RNA polymerase

6. The Central Dogma

7. Protein synthesis • the formation of proteins using information coded on DNA and carried out by RNA.

10. Transcription

11. Transcription the process of forming a mRNA strand from a DNA strand

12. Transcription Copying the DNA code to take it to the ribosomes.

13. Transcription Copying the DNA code to take it to the ribosomes. Copying the cookie recipe to take it to the bakers

14. Transcription This copies the cookie secrets in the nucleus, so the secrets don’t have to leave the safety of the nucleus.

17. Types of RNA: • Messenger RNA - mRNA • a single uncoiled strand that transmits information from DNA to the ribosomes during protein synthesis.

18. Types of RNA: • Transfer RNA - tRNA • a single folded strand that bonds with a specific amino acid

19. Types of RNA: • Ribosomal RNA - rRNA • major constituent of the ribosomes

20. Translation • Translation-the assembling of protein molecules from information encoded in mRNA.

24. Get it in your head! • DNA duplicates itself in replication. • DNA produces RNA in transcription. • RNA produces proteins in translation.
