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) Adenine (A) Guanine (G) 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 (3 letter sequence matching a codon)

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
