Deoxyribonucleic acid and ribonucleic acid -- DNA and RNA -- are closely related molecules that participate in transmitting and expressing genetic information. While they are quite similar, it's also easy to compare and contrast DNA and RNA thanks to their specific, and different, functions.
The sugar is D-ribose, which is in the group of nucleic acids called ribonucleic acids (RNA), and D-2-deoxyribose forms the basis of DNA. The 2-deoxy simply indicates the lack of an -OH group at the 2 position. Thus DNA stands for deoxyribonucleic acid. Attached to the carbon at one side of the sugar is one of the 4 bases, A, C, G, or T.
The key difference between carbohydrates and proteins is that monosaccharides or simple sugars are the monomers of carbohydrates while amino acids are the monomers of proteins. Carbohydrates and proteins are two types of macromolecules. Furthermore, they are organic compounds composed of carbon, hydrogen and oxygen atoms.
Biological polymers are large molecules composed of many smaller molecules linked together. Proteins and nucleic acids are two examples of polymers.

DNA and RNA are the two nucleic acids found in nature. Each is made of monomers called nucleotides, and nucleotides in turn consist of a ribose sugar, a phosphate group and one of four nitrogenous bases. DNA and RNA differ by one base, and DNA's sugar is deoxyribose rather than ribose.
The main substances found in every cell are a combination of lipids, carbohydrates, nucleic acids and proteins. Each of these substances plays a different role in the body, and all of them must either come from the diet or be manufactured using other chemicals in the body.
Lipids, proteins, and carbohydrates. Proteins are integral and transmembrane. The transmembrane protein span the entire membrane outside to inside and often act as transport proteins.
When these nucleic acids form sequences they create either DNA or RNA. DNA and RNA are composed of a phosphate, a sugar, and a nitrogen base. The main difference in RNA and DNA is that uracil replaces the base of thymine in RNA. Proteins are essential to maintaining cells by creating hormones and enzymes, and defending the cell.
Protein synthesis is the process whereby DNA encodes for the production of amino acids and proteins. It is a very complex and precise process and as proteins make up over half of the dry mass of a cell, it is a vital process to the maintenance, growth and development of the cell.
Academic Report on Cell Biology. Distinction.. synthesis of proteins; explain the role of nucleic acids in the nucleus and. and factors that initiate cell division; explain how the same genetic information is received by daughter cells; and compare and contrast cancer cells with normal cells.
Large carbohydrates, proteins, and nucleic acids are chain-like molecules called polymers (from the Greek polys, many, and meros, part). A polymer is a long molecule consisting of many similar or identical building blocks linked by covalent bonds, much as a train consists of a chain of cars. The repeat-.
Chemical Digestion. Large food molecules (for example, proteins, lipids, nucleic acids, and starches) must be broken down into subunits that are small enough to be absorbed by the lining of the alimentary canal. This is accomplished by enzymes through hydrolysis. The many enzymes involved in chemical digestion are summarized in Table 8.Bio.4.1.1 — Compare the structures and functions of the major biological molecules (carbohydrates, proteins, lipids and nucleic acids) as related to the survival of living organisms. Bio.4.1.2 — Summarize the relationship among DNA, proteins and amino acids in carrying out the work of cells and how this is similar in all organisms.Using your knowledge of acids, bases, and buffers, explain how pH is maintained at a constant level in this system. Compare and contrast proteins and nucleic acids. What do these biomolecules have in common? In what ways are they different? Be sure to consider both their structures and their functions.
