Question

DNA is made of monomers called_, each of which contains three subunits: a_, a_group, and a nitrogenous_. During DNA replication, one daughter strand is made continuously in the_direction and is called the_strand. It elongates_the replication fork. The other daughter strand is made discontinuously and is called the_strand. It elongates _the replication fork and is made in segments called_. Before a primary mRNA transcript is released from the nucleus of an eukaryotic cell, a modified guanine nucleotide is added to its_end and a_is added to its_end. In addition, a spliceosome removes the_and splices the_together. During translation, ribosomes use the sequence of_in the mRNA to assemble _, which are brought to the ribosomes by_molecules. The process of translation has several stages:_, which requires proteins called _;_, which requires proteins called _;and termination, which requires a_.
