Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

Directed evolution is a laboratory technique that mimics natural selection and allows scientists to evolve genes and the ...

Researchers have shown for the first time how Merkel cell polyomavirus (MCV), which causes an aggressive skin cancer called Merkel cell carcinoma, initiates DNA replication in host cells. University ...

Adult cells in our body can only give rise to the same cell type. For example, a skin cell cannot give rise to a muscle cell but to skin cells only. This limits the potential use of adult cells for ...

A viral replicon system suited to the stable replication of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), without cytopathic effects, has been reported recently in a study ...

The current model of replication-dependent (RD) histone biosynthesis posits that RD histone gene expression is coupled to DNA replication, occurring only in S phase of the cell cycle once DNA ...
