The entire genomic material of a cell must be packed into a tiny cell nucleus in such a way, that on the one hand, it can be stored in an organized manner and, on the other hand, it can be transcribed ...

The formation of four-stranded DNA has been tracked in living human cells, allowing scientists to see how it works, and its possible role in cancer. DNA usually forms the classic double helix shape ...

The formation of DNA adducts due to flavouring substances, particularly those derived from botanicals, has emerged as a critical area of toxicological research. Many naturally occurring compounds ...

A team of molecular biologists have uncovered how one particular mechanism uses energy to ensure proper histone placement onto DNA to form chromatin. The genetic material of our cells -- DNA -- exists ...

DNA replication, the fundamental process of copying a DNA molecule, is described as semiconservative due to its unique ...

This illustration shows proteins and DNA in the process of DNA repair. RecA proteins (gold) cradle a single-stranded DNA (brown) that searches for homology with a DNA template (purple). The template ...

Researchers have revealed the structural mechanisms of a major DNA repair pathway in human cells. The research, published today as a Reviewed Preprint in eLife, is described by the editors as a ...

An international collaborative research team, including scientists from the Queensland Brain Institute (QBI), has discovered a novel mechanism underlying memory involving rapid changes in a specific ...

How can human cells pack 3-meter-long DNA into their tiny nuclei and unpack it only where and when it is needed? This fascinating process is far from being completely understood. Researchers at the ...

RNA World is a fascinating theory but it may not hold true. The problem is that the ingredients, such as enzymes, to make RNA World work just didn't exist on early Earth. For decades, chemists have ...
