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?

A sugar molecule, a base, and a phosphate molecule group together to make up a nucleotide. Nucleotides are abundant in the cell's nucleus. Nucleotides are the units which, when linked sugar to ...

Each of these bases is connected to 1’-carbon of the deoxyribose sugar. In an unattached and free nucleotide, there is a triphosphate group on the 5’-carbon of the deoxyribose sugar.

Each nucleotide has three components: one sugar (deoxyribose), one phosphate, and one of the four bases-- adenine (A), cytosine (C), guanine (G), and thymine (T). All nucleotides contain the same ...

Nucleotide analogs are synthetic compounds that resemble natural nucleotides but have modifications in their structure. These modifications can involve changes in the nitrogenous base, sugar molecule, ...

The sugar in DNA is called 2-deoxyribose. These sugar molecules alternate with the phosphate groups, making up the “backbone” of the DNA strand. Each sugar in a nucleotide has a nitrogen base ...

Each nucleotide sub-unit consists of a phosphate, deoxyribose sugar and one of the 4 nitrogenous nucleotide bases. The purine bases adenine (A) and guanine (G) are larger and consist of two ...

These pairs are called base pairs and they connect the two sugar-phosphate backbones through interactions called hydrogen bonds. In cells, the DNA helix is often overwound, causing a phenomenon ...

Each of these is known as a nucleotide (consisting of a a nitrogenous base, a phosphate molecule, and a sugar molecule) and are specifically and exclusively paired, so that only A is coupled to T ...

Each ribonucleotide base consists of a ribose sugar, a phosphate group, and a nitrogenous base. Adjacent ribose nucleotide bases are chemically attached to one another in a chain via chemical ...
