The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality ...

Androgenic alopecia, commonly known as male or female pattern baldness, affects millions worldwide, offering few treatment ...

neither Levene nor any other scientist of the time knew how the individual nucleotide components of DNA were arranged in space; discovery of the sugar-phosphate backbone of the DNA molecule was ...

The famous DNA double helix is considered right-handed, meaning its spiral strands — a sugar-phosphate backbone — twist to the right. (To picture this, make a thumbs-up with your right hand ...

The backbone of the DNA double helix consists of alternating phosphate and deoxyribose sugar molecules. Interlinking bases hold the two sides together. As A is complementary to T and C is ...

The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a deoxyribose sugar, phosphate and base. The nucleotides are identical except for the base, which can be an adenine ...

Polson biochemist Ed Gannon nudges a nondescript gray chunk of rock, and then shakes a pile of round pellets into his hand. Both contain phosphate — a nutrient formed millions of years ago that's ...
