This means that one strand's sugar-phosphate chain runs in the 5 ... Crick were pursuing a definitive model for the stable structure of DNA inside cell nuclei. Watson and Crick ultimately used ...

Later it was found that the sugar in nucleic acid can ... just like the one before. This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations.

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?

Laying the Groundwork: Levene Investigates the Structure of DNA Meanwhile ... discovery of the sugar-phosphate backbone of the DNA molecule was still years away. The large number of molecular ...

Shown here is the structure of naked DNA -- DNA without all of the proteins ... The sides of the DNA ladder consist of a long string of sugar and phosphate molecules, to which the bases are ...

In its structure, DNA contains a pattern for producing amino acids, proteins, lipids, sugars, and every other biomolecule an organism makes. The parts of a DNA molecule that have these ...

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 ...

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 ...

Adenine and guanine, the two most common purines in DNA and RNA, share this core structure, which is crucial for forming ... It consists of an adenine base, a ribose sugar, and three phosphate groups.
