Let's begin in the nucleus where genetic information is stored in chromosomes Most of a persons cells are diploid with two sets of chromosomes One set is from their mother shown here in red and the other set is from their father, shown in blue Each maternal chromosome has a corresponding paternal chromosome These matched pairs are called homologous chromosomes During interphase, chromosomes are duplicated Each chromosome now consists of two identicle copies called sister chromatids Zooming in we see that each sister chromatid is made up of DNA wound around histone proteins The leakage of K+ is largely responsible for this potential. Each strand coils up into a tight helical fiber
