RNA Ribonucleic Acid – R- Ribo – N- Nucleic – A- Acid RNA- Structure Nucleotide – The monomer of RNA – Consists of 3 parts Nucleotide Part 1 5 carbon sugar – Ribose Nucleotide Part 2 Phosphate group Nucleotide Part 3 Nitrogenous bases- 4 – Purines Adenine (A) Guanine (G) Nucleotide Part 3 Nitrogenous bases – Pyrimidines Uracil (U) (replaces T of DNA) Cytosine (C) Structure Nucleotides form a single strand Types of RNA (p 205) mRNA- messenger RNA – Copies and carries the code/message from DNA to the ribosome in a cell – Contains a codon (3 letter sequence) Types of RNA (p 205) tRNA- transfer RNA – Picks up and carries the amino acids from the cytoplasm to the ribosome – Contains an anticodon Types of RNA (p 205) rRNA – ribosomal RNA – Makes up most of ribosome Comparison of DNA & RNA (p 205) 5 carbon sugar – – DNA- deoxyribose RNA- ribose Comparison of DNA & RNA (p 205) # of strands – DNA- double strand – RNA- single strand Comparison of DNA & RNA (p 205) Nitrogenous bases – DNA- A-T, C-G – RNA- A-U, C-G Comparison of DNA & RNA (p 205) Types– DNA – RNA m- messenger t- transfer r- ribosomal Comparison of DNA & RNA (p 205) Location – DNA- nucleus – RNA- nucleus, cytoplasm Protein Synthesis & Words Obtain a list of words. Put together some sentences using the list of words. Make your sentences at least 8 words long. All Images- Clip Art
