Messenger Ribonucleic Acid (MRNA) Is a Single RNA Strand Encoding

Question 1

Multiple Choice

Messenger ribonucleic acid (mRNA) is a single RNA strand encoding a "blueprint" for an amino acid sequence (e.g. a protein, after folding and posttranslational modification) . The brief existence of an mRNA macromolecule begins with transcription and ends in enzymatic hydrolysis to ribonucleotides. Whereas mRNA is basically "ready to use" after transcription in non-eukaryotes, eukaryotic mRNA requires extensive processing. In the process called 5'cap addition, a modified 7-methylguanosine ribonucleotide is added via an unusual 5' to 5' triphosphate linkage. What is the chemical structure of the 5'-end of the mRNA strand after capping?
