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?
Unlike DNA, RNA is usually single-stranded ... Each ribonucleotide base consists of a ribose sugar, a phosphate group, and a nitrogenous base. Adjacent ribose nucleotide bases are chemically ...
Later it was found that the sugar in nucleic acid can be ribose or deoxyribose, giving two forms: RNA and DNA. In 1943, American Oswald Avery proved that DNA carries genetic information.
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 ...
DNA and RNA use the same five-carbon sugar, ribose, in their structure. The deoxy- means that on one side of the base pair, there's a place where another base pair can attach itself by way of a ...
Biomolecular condensates are shifting blobs in our cells that organize cellular matter. They are distinct molecular ...
Kossel isolated cytosine from calf thymus tissues and found that it was a component of nucleic acids. This discovery, along with the identification of other nitrogenous bases, laid the foundation for ...
Genes control everything from hair color to blood sugar by telling cells which proteins ... Inside a cell is a long strand of the chemical DNA (deoxyribonucleic acid). A DNA sequence is a specific ...
When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA). This process takes place in the nucleus and occurs in a series of stages. The two ...
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 ...
