Through the technique of DNA sequencing, first developed by Frederick Sanger, scientists can determine the exact order of nucleotides in an organism’s genes. Knowing this order is the first step in ...

A Northwestern Medicine study has revealed a previously unknown connection between two fundamental cellular processes, ...

Nucleotides are the fundamental units that make up the genetic material of all living organisms. They are the building blocks of DNA and RNA, which store and transmit genetic information. Nucleotides ...

With the technique called polymerase chain reaction (PCR), scientists can make multiple copies of a specific genetic sequence within DNA. PCR is a powerful tool for researchers because it allows for ...

Chemists have demonstrate that they can repurpose DNA to create new substances with possible medical applications. DNA evolved to store genetic information, but in principle this special, chain-like ...

For the first time, scientists have developed artificial nucleotides, the building blocks of DNA, with several additional properties in the laboratory. The DNA carries the genetic information of all ...

DNA is known for being a storehouse of genetic information. Just one gram of the genetic material can theoretically hold some 300,000 terabytes of information, far exceeding the roughly 5 terabytes ...

Whether it is a microbe, a rose, or a dolphin, any form of life gets its building and operating instructions from the molecule of life, DNA. DNA comprises the genes and chromosomes that govern the ...

Yesterday the Royal Swedish Academy of Sciences awarded the Nobel Prize in Chemistry to Tomas Lindahl, Aziz Sancar, and Paul Modrich for their work in mapping out how cells repair damaged DNA. Their ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

In 1869, Friedrich Miescher discovered DNA. About seventy years thereafter, Oswald Avery and his colleagues proved that DNA carries genetic information. A decade later, James Watson and Francis Crick ...

This diagram depicts the chemical structure of pyrimidine, a six-membered aromatic ring with two nitrogen atoms at positions 1 and 3 (highlighted in blue). The remaining positions are occupied by ...
