16. DNA to protein

17. DNA
NEVER leaves the cell’s nucleus

18. RNA
Single stranded

20. RNA
Single stranded
Sugar is ribose

21. RNA Single stranded Sugar is ribose
Uses Uracil (u) in place of thymine

22. RNA Single stranded Sugar is ribose
Uses Uracil (u) in place of thymine
3 types:
mRNA, rRNA & tRNA

24. PROTEIN SYNTHESIS
2 parts

25. TRANSCRIPTION
DNA sends instructions to ribosomes as mRNA

26. TRANSCRIPTION DNA sends instructions to ribosomes as mRNA
RNA polyermase separates DNA strands

27. TRANSCRIPTION DNA sends instructions to ribosomes as mRNA
RNA polyermase separates DNA strands
One strand of DNA used as a template

28. TRANSCRIPTION DNA sends instructions to ribosomes as mRNA
RNA polymerase separates DNA strands
One strand of DNA used as a template
Copy of mRNA is made

29. mRNA leaves the nucleus and travels to the ribosomes
