Bailey Lucas, an undergraduate Pelotonia fellow majoring in zoology at Ohio State Marion, discusses the Pelotonia Fellowship Program, and cancer research she participates in, which is focused on, DNA damage repair through homologous recombination. Homologous recombination is a type of genetic recombination in which nucleotide sequences are exchanged between two similar or identical molecules of DNA. It is most widely used by cells to accurately repair harmful breaks that occur on both strands of DNA, known as double-strand breaks (DSB).
