A specialized class of proteins called histones organizes the double-stranded DNA into what looks like a tightly coiled telephone cord. Genomics refers to the study of all of the genetic material within cells and encompasses the environmental interaction and impact on biologic and physical characteristics. Each somatic chromosome, also called an autosome, is made of two strands, called chromatids, which are joined near the center. A karyotype is the arrangement of human chromosomes from largest to smallest.
