Each chromosome consists of an unbroken strand of DNA inside the nucleus of the cell. This arrangement of human chromosomes is known as:
a. chromatids. c. genomics.
b. karyotype. d. histones.
B
A karyotype is the arrangement of human chromosomes from largest to smallest. Each somatic chromosome, also called an autosome, is made of two strands, called chromatids, which are joined near the center. 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. A specialized class of proteins called histones organizes the double-stranded DNA into what looks like a tightly coiled telephone cord.
