Beyond the ladder-like structure described above, another key characteristic of double-stranded DNA is its unique three-dimensional shape. The first photographic evidence of this shape was ...

Members of the same species usually have DNA similar enough to have the same chromosomes and autosomes (chromosomes that don't code for sex-linked traits). In its structure, DNA contains a pattern ...

Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. All living things have DNA within their ...

Each nucleotide consists of alternating sugar and phosphate sections with one of the four different bases attached to the sugar.

Earlier that morning, in the nearby Cavendish laboratory, the two scientists had discovered the structure of deoxyribonucleic acid, or DNA. This discovery changed the world of science and medicine ...

This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations. The structure so perfectly fit the experimental data that it was almost immediately ...

What is it made of, and what is its function in living things? How do we study the molecular structure of DNA? And why do ...

What if you could take a picture of every gene inside a living organism—not with light, but with DNA itself? Scientists at ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...

Scientists at EMBL have captured how human chromosomes fold into their signature rod shape during cell division, using a ...

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 ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves.
