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 ...

Study details how mitochondria organize and pass on their DNA
Researchers have identified a physical process called “mitochondrial pearling” that explains how cells keep their ...
A team of researchers at VCU Massey Comprehensive Cancer Center has identified a new pathway through which mutations in the tumor suppressor p53 gene—found very frequently in human tumors—hijack DNA ...
Scientists reveal a hidden second layer of human DNA, showing how genome folding controls genes and influences disease development.
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 ...
Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...
Scientists used a bacterial system called retron to turn DNA into a programmable tool inside living cells, enabling gene ...
Researchers discovered a kinase-driven phosphorylation switch that activates DNA packaging machinery, aligning nucleosomes at ...
