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

The double-stranded DNA that results from this pattern of bonding looks much like a ladder with sugar-phosphate side supports and base-pair rungs.

DNA is a molecule that exists in almost every living thing, telling it what it should look like and how it should function. Learn more about the building block of life.

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

Understanding where and in what quantities essential elements for life have existed on Earth's surface helps explain the ...

DNA, or deoxyribonucleic acid, is fundamental to your growth, reproduction, and health. Read about its basic function and structures.

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that make up the human genome. But where and how does the famous double helix fit into ...

Nucleotides are the units which, when linked sugar to phosphate, make up one side of a DNA ladder. During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as ...

The nuclear protein FUS, which accumulates in the cytoplasm in some forms of frontotemporal dementia and amyotrophic lateral sclerosis (ALS), gets its marching orders from the DNA repair machinery, ...

Urine contains DNA but only in small amounts, and it deteriorates quickly. This makes extraction difficult and test results unreliable. Learn more about the DNA in your urine, and what clues it ...

DNA consists of two strands, that wind around each other. Each strand has repeating units of a nitrogenous base, deoxyribose sugar, and a phosphate group. There are several interactions present ...
