Which . of the following statements best describes the structure of DNA. ?. A. . Two strands of proteins are held together by sugar . molecules. , . nitrogen bases, and . phosphate groups.. B. . Essential idea: The structure of DNA allows efficient storage of genetic information.. There is 2m of DNA in each human cell, however the most cells in the human body have a diameter of 10 . μm. . This DNA is divided in chromosomes and coiled around proteins called histones so that it can be efficiently stored in each cell's nucleus. The human genome project which has decoded the case sequence for the whole 2m of the human genome requires a data warehouse (pictured) to store the information electronically. This should give a good idea of just how efficient DNA is at storing information and why it needs to be so.. Biomolecules. Organic molecules made up of:. Carbon. Hydrogen. Nitrogen. Oxygen. a. nd sometimes Phosphorus. LATIN 101. Poly = . Many. Mono = . O. ne. Hydro = . Water. . (actually Greek). Synthesis = .
