DO NOW▸What are proteins made out of?
▸What determines protein structure?
▸What is the name of the sugar in DNA?
▸Where in the cell is DNA located?
▸Draw a picture of the cell, its nucleus, and DNA within the cell
▸(take out HW and show me your summary if I haven’t stamped it yet)
AGENDA▸ RNA
▸ Introduction to protein synthesis

GLOW IN THE DARK
• Glow in the dark!
• Write down 3 questions about the content of the video.
GLOW IN THE DARK!• How did scientists do this?
• Are there any side effects?
• What could be useful about using this method/technology?

RNA (SINGLE NUCLEOTIDE)
PAGE 103
RNA▸ Ribonucleic Acid
▸ 5-carbon sugar = ribose
▸ Single stranded
▸Made of nucleotides
▸ Has Uracil instead of Thymine
PAGE 103
3 TYPES OF RNA▸mRNA
▸ tRNA
▸ rRNA
PAGE 103
mRNA▸ Messenger RNA
▸ Carry code from nucleus to ribosomes
Why would DNA need a messenger?
PAGE 103
tRNA▸ Transfer RNA
▸ Transfer “free floating” amino acids to the ribosomes
PAGE 103
rRNA▸ Ribosomal RNA
▸ Component of ribosome
PAGE 103
RIBOSOMES▸Made of proteins and rRNA
▸Makes proteins

• Annotate the text (Story of a Castle and DNA, Transcription and Translation Story)
TRANSCRIPTION AND TRANSLATION: ANALOGY STORY
• Annotate Part I• Answer questions in Part 1, Part 2, and Part 3
QUESTIONS?• We will continue our discussion on cats
that glow in the dark, how the DNA code is decoded, and how proteins are made NEXT TIME! :)
