The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...
Eukaryotic chromosomes replicate from multiple discrete loci termed origins of replication. These sites are first recognised by the origin recognition complex (ORC), which, together with Cdc6 and Cdt1 ...
Scientists have uncovered a surprising twist in how cells behave when division goes wrong. Sometimes a cell successfully copies its DNA but fails to split into two, leaving it with double the genetic ...

The DNA from a single human cell would stretch about two meters if pulled into a line
Stretched into a single line, the DNA packed inside one human cell would reach roughly two meters, yet it folds into a ...

Scientists just caught cells quietly copying their DNA but forgetting to split in two — leaving them with double the genetic material in a glitch now tied to cancer and agi…
A cell copies all six billion letters of its DNA, gears up to split, and then simply… doesn’t. It sits there, swollen with ...
When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...
A representative figure showing that HELQ-deficient cells fail to undergo normal fork slowing after MMC (a crosslinking agent) treatment, consistent with defective fork reversal. Every time a cell ...
It's tricky to make an exact copy of yourself. Or at least it is for cells undergoing mitosis, where cells replicate ...
In each cell of your body, DNA is stored in structures called chromosomes. When cells divide, these chromosomes are copied, ...
The left-handed spiral of each Z-DNA strand is highlighted on the left. Binding and bonding of the two zinc finger domains (shown in red) from the CTCF protein to Z-DNA (shown in blue). This protein ...
