Before a cell divides and DNA is passed from one cell to another, a complex process occurs. The DNA strands unwind and separate. Each strand makes a complementary strand by adding the appropriate ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular aging, cancer, ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

In a twist on the question, 'Which came first, the chicken or the egg?', scientists have long faced a similar question about how human adenovirus replicates: 'Which comes first, assembly of the viral ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study. In a new paper published in Nature Communications, an ...

Every person starts as just one fertilized egg. By adulthood, that single cell has turned into roughly 37 trillion cells, many of which keep dividing to create the same amount of fresh human cells ...

If the engines of DNA replication stay in high gear all the time, they eventually stall or even break down. Fortunately, these engines, which consist of protein complexes, have what could be called ...

An elegant collaboration between researchers in the UK's two core-funded Medical Research Council Research Institutes, the Laboratory of Medical Sciences (LMS) in London and the Laboratory of ...
