To actually visualize the double-helical structure of DNA, researchers require special ... To see chromosomes in this way, scientists must first use a chemical process that attaches the ...

Levene Investigates the Structure of DNA Meanwhile, even as Miescher's name fell into obscurity by the twentieth century, other scientists continued to investigate the chemical nature of the ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

Most microscopes can only illuminate objects down to a certain size before tiny features blur together. This blurring is ...

According to UCSD, there are two prevailing theories about the relationship between aging and our DNA. The somatic mutation theory suggests aging is caused by an accumulation of mutations leading to ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single ... The central dogma of molecular biology describes the flow ...

A recent study by researchers from Peking University demonstrates the potential of nuclear electric resonance to control the nuclear spins of nitrogen atoms in DNA using electric field gradients, ...

Genes exist in most cells. Inside a cell is a long strand of the chemical DNA (deoxyribonucleic acid). A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA ...

A team has unearthed new findings about what happens during the minutes and hours after a cell divides, expanding our understanding of human biology -- and potentially leading to better medicines.
