Eukaryotic mRNA: a. uses snRNPs to cut out introns and seal together translatable exons. b. uses a spliceosome mechanism made of DNA to recognize consensus sequences to cut and splice. c. has a guanine cap on its $3^{\prime \prime}$ end and a poly(A) tail on its $5^{\prime}$ end. d. is composed of adenine, thymine, guanine, and cytosine. e. codes the guanine cap and poly(A) tail from the DNA template.
which of the following is NOT a modification of a mature mRNA transcript? a. methyl cap added to the 5' end b. poly a tail added to the 3' end c. introns are spliced out d. alternative introns are spliced e. a and c only
