Researchers have revealed the structural mechanisms of a major DNA repair pathway in human cells. The research, published ...

meaning that the ends of each strand are free. In a prokaryotic cell, the DNA forms a circular structure. DNA contains the instructions that are necessary for an organism to grow, develop ...

to form the iconic double helix structure. RNA is usually single-stranded but can form complex secondary structures through base pairing within the same strand. DNA serves as the repository of genetic ...

Cells have effective DNA repair mechanisms ... of DNA double-strand breaks causes excessive methylation of NEAT1, which leads to changes in the NEAT1 secondary structure. As a result, highly ...

A G-quadruplex comprises four guanines from different places along a G-rich strand held together by a special type of hydrogen bonding to form a compact square structure that interrupts the DNA helix.

Mitochondrial DNA is compact in structure and typically lacks non-coding regions (introns ... of dsDNA are displaced and separated by a third strand which is base-complementary to one of the ...
