  1. Ch. 11.4 & 11.5 NotesRNA & Transcription

  2. _____ _____ _ _ _ _ _ _ _ PROTEIN!! It makes you look like you R E N DNA RNA P O T I

  3. Transcription Translation RNA uses DNA’s instructions to make protein Ribonucleic Acid

  4. Same structure – they’re both made of nucleotides • Sugar in RNA = ribose • RNA has base “U” instead of “T” • RNA is single stranded Double-stranded Single- stranded Base pairs are A-T & C-G Base pairs are A-U & C-G Sugar= deoxyribose Sugar= ribose

  5. RNA vs. DNA

  6. It copies the DNA code (message) and brings it to the ribosome Brings the instructions from the boss (DNA) to the assembly line (ribosome) Messenger RNA (mRNA) Uses instructions from the boss (DNA) to put the car (protein) together Ribosomal RNA (rRNA) It is the ribosome! It brings the amino acids to that are used to build the protein Transfer RNA (tRNA) Delivers parts (amino acids) needed to build the car (protein)

  7. mRNA is made from DNA DNA unzips. RNA nucleotides match up with ONE SIDE of the DNA mRNA is removed from DNA, leaves the nucleus, and goes to the cytoplasm. DNA zips back up. *Remember that RNA has “U” and not “T”

  8. What Transcription looks like:

  9. It is an enzyme that links the RNA nucleotides together in the new strand of RNA nucleus that is where the DNA is and the DNA cannot leave the nucleus.
