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?

DNA analysis is crucial for identifying individuals and their relatives, using technologies like PCR, electrophoresis, and ...

Embodied in the sequence of base pairs, DNA carries information between generations ... To maintain its orderly structure, ...

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 ...

We've now zoomed in enough to see portions of the DNA strand. The DNA is wrapped ... of the DNA ladder consists of two bases. In the DNA molecule, A always pairs up with T, and C always pairs ...

As previously mentioned, the location at which a DNA strand begins to unwind into two ... vary in length (from about 200 to 1,000 base pairs) and sequence, except among closely related organisms ...

Genes exist in most cells. Inside a cell is a long strand of the chemical DNA (deoxyribonucleic acid). A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA ...

Using the 4 possible combinations of base pairs as a binary system ... This involves carefully selecting the length and sequence of each DNA strand to ensure that it will bind to the appropriate ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...

Researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer.
