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?

Our DNA contains about 80,000 genes. A DNA molecule has two strands which twist around each other to form a spiral. Genetic information is encoded along these strands. If the code was written out ...

The parts of a DNA molecule that have these instructions are called genes. An individual's genome is the sum total of their ...

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 ...

As early as 1943 Oswald Avery proved what had been suspected: that DNA, a nucleic ... picture of the molecule's structure, by how the X-rays bounced off its component parts. Franklin, a shy ...

What do a human, a rose, and a bacterium have in common? Each of these things — along with every other organism on Earth — contains the molecular instructions for life, called deoxyribonucleic ...

DNA sequencing is a laboratory method used to determine the sequence of a DNA molecule. The method was developed by Frederick Sanger in 1975, who was later awarded the Nobel Prize in chemistry in ...

The DNA molecule was composed of the traditional sugar backbones and nucleotide pairs, but rather than the well-known right-handed spiral of the double helix structure, famously discovered by Watson ...

The parts of a DNA molecule that have these instructions are called genes. An individual's genome is the sum total of their genes. Two nucleotides together form a base pair; the sugars and ...

Each strand can be used as a template to create a new DNA molecule. Free DNA nucleotides – needed to form the new strands. DNA polymerase – an enzyme that adds new nucleotides to a growing str ...
