New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as intricate as once thought. Half a century ago, scientists Jim Watson and Alexey Olovnikov ...
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 ...
During the replication of the bacterial chromosome, genes close to the replication start point (red) exist in multiple copies, while genes close to the endpoint do not (blue). At faster growth, this ...
Half a century ago, scientists Jim Watson and Alexey Olovnikov independently realized that there was a problem with how our DNA gets copied. A quirk of linear DNA replication dictated that telomeres ...
