BIOL 1000 Chapter Notes - Chapter 4: Rna World, Deoxyadenosine, Dehydration Reaction
Document Summary
These are the nucleotides used to make rna: datp, dctp, dgtp, and dttp (thymidine) are all dntps (deoxynucleoside triphosphates). These antiparallel strands were predicted to form a double helix: every 10 bases, the structure completes a full helical turn which was the. Instead of dntps, rna consists of ntps (atp, gtp, ctp, and utp: rna contains ribose instead of deoxyribose, rna contains uracil instead of thymine, secondary structure. Like dna, rna has a secondary structure that results from complementary base pairing. Different lengths and arrangements produce different structures: tertiary structure, rna forms tertiary structures when the secondary structure folds to form a 3-d shape, functions, since rna is made of nucleotides it also carries information. This is useful in transcription, translation, and protein synthesis: rna can also catalyze reactions because of the large variety of potential structures. In search of the first life form: the theory of chemical evolution relies on the premise that life began as a self-replicator.
