Processing of these molecules after they are produced may involve using a 5'-5' [Five prime to five prime] -triphosphate linkage to create a cap, adding a(*) poly(A) tail, and splicing out introns.
Mirtrons are a class of the "micro" variety of these molecules that bypass Drosha processing. Some of these molecules have catalytic properties, suggesting that self-replicating kinds were precursors of life. Processing of these molecules after they are produced may involve using a 5'-5' [Five prime to five prime] -triphosphate linkage to create a cap, adding a(*) poly(A) tail, and splicing out introns. Rather than use thymine like a similar double- stranded molecule, these molecules contain uracil. Ribose, not deoxyribose, is used in the backbone of, for 10 points, what single-stranded nucleic acid?
