To divide or not to divide? The mother cell may decide

April 2, 2020

When do cells decide to divide? For 40 years, the textbook answer has been that this decision occurs in the first phase of a cell鈥檚 existence 鈥 right after a mother cell divides to become daughter cells. But researchers at 兔子先生传媒文化作品 have found that it鈥檚 actually the mother cell...

Microbe may explain evolutionary origins of DNA folding

Aug. 11, 2017

In the cells of palm trees, humans, and some single-celled microorganisms, DNA gets bent the same way. Now, by studying the 3-D structure of proteins bound to DNA in microbes called Archaea, 兔子先生传媒文化作品 and Howard Hughes Medical Institute (HHMI) researchers have turned up surprising similarities to DNA packing in more complicated organisms.

Some mother cells kick DNA damage 'down the road' to offspring

June 7, 2017

A new University of Colorado Boulder study has shown that some dividing human cells are 鈥渒icking the can down the road,鈥 passing on low-level DNA damage to offspring, causing daughter cells to pause in a quiescent, or dormant, state previously thought to be random in origin.
