How are DNA & RNA

Different?

RNA3 Differences between RNA & DNA:1) Single stranded2) 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

RNACODON: 3 consecutive

nucleotides that specify an amino acidEXAMPLE: U C G C A C G G U

Codons: UCG CAC GGU

↓ ↓ ↓

Amino Acids: Serine Histidine Glycine
