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?

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 ...

Cytosine (C) will "pair" to guanine (G), and adenine (A) will "pair" to thymine (T). How the bases are arranged in the DNA is what determines the genetic code. When the enzyme has passed the end ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

Each rung of the DNA ladder consists of two bases. In the DNA molecule, A always pairs up with T, and C always pairs up with G. The sides of the DNA ladder consist of a long string of sugar and ...

Erwin Chargaff's groundbreaking research, which showed that DNA base pairs had a complementary relationship, laid the foundation for James Watson's and Francis Crick's DNA model. When word spread that ...

This phenomenon is known as complementary base pairing (Figure 4), and it results in the production of two complementary strands of DNA. Base pairing ensures that the sequence of nucleotides in ...

An STR is a short sequence of base-pairs on the DNA that is repeated some number of times, such as GATCGATCGATCGATC (on the complementary strand, this STR will have the sequence CTAGCTAGCTAGCTAG).
