A nucleic acid is a long molecule made up of smaller molecules called nucleotides. Nucleic acids were discovered in 1868, when twenty-four-year-old Swiss physician Friedrich Miescher isolated a ...

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?

Scientists have transformed RNA, a biological molecule present in all living cells, into a biosensor that can detect tiny ...

The resulting RNA molecule, typically mRNA, carries the genetic message from the nucleus to the cytoplasm for protein synthesis. Nucleic acids are the foundation of genetic engineering techniques, ...

How did scientists discover and unlock this amino acid code? Once the budding molecular biology community was convinced about the triplet code, the race to decode which triplets specified which ...

Fully assembled, the sequence of base pairs is a compound molecule called a nucleic acid. Living organisms are constantly building new cells or repairing old ones. To do this they have to make ...

Most people at the time thought the gene would be protein, not nucleic acid, but by the late 1940s, DNA was largely accepted as the genetic molecule. Scientists still needed to figure out this ...

Nucleic acids are the backbone of molecular biology research. As such, preservation of their integrity and purity is fundamental for genomic research. Low quality samples can lead to inconsistent ...

Aptamers can be labeled with fluorescent dyes or radionuclides for molecular imaging applications. They can be used to visualize specific targets in vitro or in vivo, aiding in the diagnosis and ...

Scientists have uncovered a surprising role for calcium in shaping the building blocks of life. Their study reveals that calcium ions help determine the molecular 'handedness' (chirality) of tartaric ...

Hajun Kim, Taejoon Kwon, and Joo Hun Kang—from the Department of Biomedical Engineering at UNIST has unveiled a novel diagnostic technique that utilizes artificially designed polymers known as peptide ...

Recent advancements in circulating nucleic acids, including cf-DNA and cf-RNA, have improved diagnostics and monitoring ...
