Researchers show that four-stranded DNA is formed and unfolded

Researchers at Umeå University in Sweden have discovered that specific DNA sequences that are rich in the DNA building block guanine in the yeast species, Schizosaccharomyces pombe, can form four-stranded DNA. In a study ...

Sixty-year-old question on DNA replication timing sequence answered

Over the last 60 years, scientists have been able to observe how and when genetic information was replicated, determining the existence a "replication timing program," a process that controls when and in what order segments ...

DNA replication machinery captured at atom-level detail

July 15, 2019) Life depends on double-stranded DNA unwinding and separating into single strands that can be copied for cell division. St. Jude Children's Research Hospital scientists have determined at atomic resolution the ...

Researchers uncover human DNA repair by nuclear metamorphosis

Researchers at the University of Toronto have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and premature aging.

New insight into the possible origins of life

Researchers at the University of Tokyo have for the first time been able to create an RNA molecule that replicates, diversifies and develops complexity, following Darwinian evolution. This has provided the first empirical ...
