During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as it moves along. New nucleotides move in to each side of the unzipped ladder. The bases on these ...

the DNA replication checkpoint is the master surveillance system that steps in when a cell has problems during DNA replication. What does the DNA replication checkpoint really monitor? This ...

New research shows that DNA replication in early mouse embryos doesn't follow the expected patterns seen in older cells. A ...

Scientists have identified the likely geological and environmental conditions that fostered the development of life as we ...

Telomere shortening and DNA damage play crucial roles in aging, a multifaceted biological phenomenon characterized by a ...

Previous research suggests that about two thirds of the mutations that drive cancer result from errors made during DNA replication. DNA replication is an essential part of cell division. Before a cell ...

The fundamental building blocks of genetic material may have replicated on their own, potentially giving rise to life on ...

A centromere is a specialized location in the DNA that functions as the control center of cell division and is maintained, ...

What is DNA, and how does it work? You don't need a degree in genetics to understand. Here, we'll give an overview of DNA and answer questions like these: What does DNA stand for? What is it made of, ...

Errors in non-coding regions are detected during cell renewal, which requires the creation of a new copy of the genome each time, via the process of DNA replication. However, cell renewal does not ...

The National Institutes of Health has awarded $1 million to the Oklahoma Medical Research Foundation to study how the ...

Thymine dimers are a common type of UV-induced DNA lesion and are associated with skin cancer risk. During DNA replication, the complementary base pairing of thymine with adenine ensures the accurate ...
