Cell resiliency surprises scientists
Date:4/24/2014

d grow just fine, indicating that they were still managing to make more DNA without DNA Ligase I. They even saw that these 'handicapped' cells were able to fix induced damages in the DNA as well.

"Our next question is whether this phenomenon is unique to this specific type of cell, or if it's generally true to a variety of other cells, including those of humans," Yu said. "We're interested in finding out how exactly the cell's adapting."

If the replacement of DNA Ligase I is in fact a general rule among many types of cells, then textbooks will have to be rewritten, and scientists will have to start working toward a better explanation of how DNA is maintained and copied in the cell two processes that are essential to the viability of life.
