DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality ...

DNA and RNA use the same five-carbon sugar, ribose, in their structure. The deoxy- means that on one side of the base pair, there's a place where another base pair can attach itself by way of a ...

They are the building blocks of DNA and RNA, which store and transmit genetic ... (Image: Public Domain) Ribonucleotides are the building blocks of RNA. They contain ribose as the sugar molecule and ...

Unlike DNA, RNA is usually single-stranded ... Each ribonucleotide base consists of a ribose sugar, a phosphate group, and a nitrogenous base. Adjacent ribose nucleotide bases are chemically ...

It is a polymeric molecule composed of nucleotides, each containing a ribose sugar, a phosphate group, and one of four nitrogenous bases: adenine (A), uracil (U), guanine (G), or cytosine (C). RNA is ...

Later it was found that the sugar in nucleic acid can be ribose or deoxyribose, giving two forms: RNA and DNA. In 1943, American Oswald Avery proved that DNA carries genetic information.

Genes control everything from hair color to blood sugar by telling cells which proteins ... Inside a cell is a long strand of the chemical DNA (deoxyribonucleic acid). A DNA sequence is a specific ...
