WebRNA is a unique polymer. Like DNA, it can bind with great specificity to either DNA or another RNA through complementary base pairing. It can also bind specific proteins or small molecules, and, remarkably, RNA can catalyze chemical reactions, including joining amino acids to make proteins. All the RNA in cells are themselves copies of DNA ... WebJul 7, 1998 · Therefore to get greater stability it may be necessary to use bases other than these pyrimidines (56, 57) or to use an all-purine helix (excluding hypoxanthine and isoguanine). In addition, the instability of all of the alternatives measured ( t 1/2 < 1 yr at 100°C) indicates that these compounds also would be excluded from use in a high …
