Chapter 4, Problem 7TYU
Summary Introduction
To review:
The relation between complementary base pairing in a DNA (deoxyribonucleic acid) and the Chargaff’s rule. Whether this rule applies to RNA (ribonucleotide molecule) or not.
Introduction:
DNA is the genetic material that is present in all living cells. It is in the form of a double helix and contains the information that is inherited by the progeny. The information on DNA is expressed in the form of proteins that carry out the basic functions of all the cells. For translation of the genetic code into proteins, an intermediary molecule called RNA has to be formed.

The DNA strands are oriented in an antiparallel direction.
Phosphate groups and deoxyribose form the outside backbone of the double stranded DNA molecule.
Nucleotides are always composed of a pentose sugar, phosphate, and nitrogenous base.
