In dna replication in e. coli, the enzyme primase is used to attach a 5 to 10 base ribonucleotide strand complementary to the parental dna strand. the rna strand serves as a starting point for the dna polymerase that replicates the dna. if a mutation occurred in the primase gene, which of the following results would you expect?

How is ribosomal rna useful as a molecular clock? a. a large portion of the dna ring is not vital to structure or function, allowing it to accumulate neutral mutations. b. its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. c. a slow mutation rate makes it useful for determining evolutionary relationships between ancient species. d. it is only found in select organisms, making it easier to compare relationships between species that have it.

How are proteins and nucleic acids related? they both provide energy. they both carry genetic information. the structure of proteins is determined by nucleic acids. the subunits of nucleic acids are also the subunits of proteins.
