Nucleic Acids: DNA and RNA

Nucleic acids allow organisms to transfer genetic information from one generation to the next. There are two types of nucleic acids: deoxyribonucleic acid, better known as DNA and ribonucleic acid, better known as RNA.

DNA contains the "programmatic instructions" for cellular activities. When organisms produce offspring, these instructions, in the form of DNA, are passed down.

RNA is involved in the synthesis of proteins. Information is typically passed from DNA to RNA to the resulting proteins.

The Structure of Carbs

Ah, the sweet taste of sugar. Most of us love and adore its taste. Sugar and its derivatives are called carbohydrates.

Carbohydrates can be simple sugars (monosaccharides), double sugars (disaccharides), or can contain many sugars (polysaccharides).

Examples of carbohydrates include glucose, sucrose, starch, cellulose and glycogen.
