Unformatted text preview: the circle, it is incorporated into the genetic code when the bacteria reproduces. Society benefits from this procedure because it allows for research on how to cope with genetic disorders in human beings. This technique is an example of how scientists build on previous research and experiments and push further to discover new things. What started as an experiment done by Griffith to discover bacterial transformation led to Hershey and Chase using bacteriophages to study the role of DNA in overseeing production of new viral particles. 3) Regulation During DNA replication in eukaryotes, DNA molecules use telomeres at their ends that contain multiple repetitions of a short nucleotide sequence. Over many generations of time, the telomeres grow shorter to compensate for the nucleotides used up in replication. Therefore, an enzyme called telomerase is used to catalyze lengthening of telomeres over time and restore those that become unusable....
