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?

Each strand has repeating units of a nitrogenous base, deoxyribose sugar, and a phosphate group. There are several interactions present within a strand and between two strands that stabilize the DNA.

Cytosine is one of the four main nitrogenous bases found in DNA and RNA, along with adenine (A), guanine (G), and thymine (T) or uracil (U). It is a pyrimidine derivative, meaning it has a single-ring ...

This base-to-base bonding is not random; rather, each A in one strand always pairs with a T in the other strand, and each C always pairs with a G. The double-stranded DNA that results from this ...

Building on previous work on the development of X and Y in 2014, the team demonstrated at the time that engineered E. coli bacteria could hold the artificial base pair in their genetic code ...

DNA is a molecule that exists in ... a phosphate group, and one of four nitrogen-containing bases. In ... of these base pairs is critically important because it determines the genetic ...

These bases are the rungs of the DNA ladder. (It takes two bases to form a rung -- one for each side of the ladder.) A sugar molecule, a base, and a phosphate molecule group together to make up a ...

DNA, or deoxyribonucleic acid, is fundamental to your growth, reproduction, and health. Read about its basic function and structures.

This phenomenon is known as complementary base pairing (Figure 4), and it results in the production of two complementary strands of DNA. Figure 5: A new DNA strand is synthesized.

DNA consists of two strands, arranged in a double helix. These strands are made up of subunits called nucleotides. Each nucleotide contains a phosphate, a 5-carbon sugar molecule and a nitrogenous ...
