[4] write the correct name of the nucleoside portion under each molecule given below. Circle the correct answer: [2] histones are _______ that are usually associated with _________, acidic proteins; dna, acidic proteins; rna, basic proteins; dna, basic proteins; rna, coenzymes derived from histidine; enzymes. Circle the correct answer: [4] a suitable substrate for dna polymerase is shown below. Label the primer and template, and indicate which end of each strand must be 3" or 5". Nevertheless, during semiconservative dna replication in the cell, entirely new daughter dna chains are synthesized. Explain the process that occurs in the cell that allows for the synthesis of daughter chains by dna polymerase.
