RNA

RNA RNA: Ribonucleic Acid. Takes info in DNA to create proteins DNA RNA PROTEIN

RNA How are DNA & RNA Different?

RNA 3 Differences between RNA & DNA: 1)Single stranded 2)Ribose instead of deoxyribose (sugars) 3)Uracil (U) instead of Thymine (T)

RNA S = Ribose (sugar) U = Uracil (nitrogenous base) P = Phosphate group

RNA mRNA: carries copies of instructions from DNA rRNA: part of ribosomes-where proteins are assembled tRNA: transfers each amino acid to the ribosome

RNA What is an amino acid?

RNA RECALL: 20 types of amino acids & proteins are a combo of any or all amino acids strung together

RNA RNA POLYMERASE: enzyme like DNA Polymerase

RNA TRANSCRIPTION: RNA Polymerase binds to DNA & separates the strands. It then uses 1 strand as a template from which nucleotides are assembled into a RNA strand

RNA

RNA CODON: 3 consecutive nucleotides that specify an amino acid EXAMPLE: U C G C A C G G U Codons: UCG CAC GGU ↓ ↓ ↓ Amino Acids: Serine Histidine Glycine 64 possibilities so use a codon chart
