The ribosomes’s primary function in both prokaryotic cells and eukaryotic cells is to A. Build proteins according to the cell’s DNA instruction
B. Create RNA
C. Replicate DNA and RNA
D. Produce amino acids to be used to make tissues

is required so that group of cells called tissues may have different function.
A. Cell interaction
B. Cell differentiation
C. Cell Proliferation
D. Cell Movement

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.
