This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...

Scientists reveal a hidden second layer of human DNA, showing how genome folding controls genes and influences disease development.

Researchers have identified a physical process called “mitochondrial pearling” that explains how cells keep their ...

DNA–protein cross-links (DPCs) represent a severe form of DNA damage that can disrupt essential chromatin-based processes. Among them, DNA–histone cross-links (DHCs) occur frequently within ...

A change in the DNA sequence of a codon may not change the corresponding amino acid residue in the encoded protein because each residue can be encoded by several codons. This is called the Wobble ...

Researchers discovered a kinase-driven phosphorylation switch that activates DNA packaging machinery, aligning nucleosomes at ...
