It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.
<h3>How are isotopes used in radioactive dating?</h3>
These isotopes decay within the rocks according to their half-life rates, and by choosing the fit minerals and measuring the relative amounts of parent and daughter isotopes in them, the date at which the rock crystallized can be determined.
Thus, It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope.

Answer:
RNA polymerase uses one of the DNA strands (the template strand) as a template to ... and death, because no new RNAs—and thus, no new proteins—can be made. ... During this process, the DNA sequence of a gene is copied into RNA. Before transcription can take place, the DNA double helix must unwind near the gene
