Essay / Research Paper Abstract
A 7 page research paper on nucleic acids. There are two nucleic acids -- deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)--that provide the "blue prints" or templates for building all of the hundreds of thousands of proteins required by the bodies of living organisms. This paper provides a basic introduction into their structure and function. Bibliography lists 3 sources.

operating efficiently. This role is performed by nucleic acids. The following examination looks at the two major categories of nucleic acids, their function and structure. There are two nucleic acids
-- deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)--that provide the "blue prints" or templates for building all of the hundreds of thousands of proteins required by the bodies of living
organisms (Carpi, 2004). In other words, the vast amount of information that is needed for the muscles, bones and tissue of a complex organism to function properly is stored and
transmitted using nucleic acids. Besides storing and transmitting information, RNA also serves structurally and functionally within some bodily units, such as the ribosome and in some systems provides a
catalytic function (NTRC, 2004). Nucleic acids are large molecules that consist of two basic parts. The supporting structure of a nucleic acid is composed of alternating sugar and phosphate
molecules that are bonded together in a long chain. Each of the sugar groups in the supporting structure, the "backbone" of the molecule, is attached to a third
type of molecule which is known as a nucleotide base (Carpi, 2004). There are only four different nucleotide bases. The order in which these nucleotide bases appear within the nucleic
acid determines the information that is carried by the molecule. In other words, the nucleotide bases provide a "genetic alphabet" that provides the structure of every protein within the body
of a living organism (Carpi, 2004). The nucleotides that make up DNA and RNA are held in strands that are bridged by a phosphate group that connects the number
5-carbon position of one sugar to the number 3-carbon position of the next sugar in line. This arrangement gives the backbone chain of the molecule a structure that alternatives between
