Arthur Kornberg compared DNA to a tape recording of instructions that can be copied over and over. How do cells make these near-perfect copies, and does the process ever vary? In reality, the process ...

Termination of DNA replication occurs when two replication forks meet on the same stretch of DNA, during which the following events occur, although not necessarily in this order: forks converge until ...

DNA, often called the blueprint of life, is built from four chemical building blocks known as deoxy-nucleoside triphosphates (dNTPs)—dATP, dTTP, dGTP, and dCTP. Cells constantly need these molecules ...

Your support goes further this holiday season. When you buy an annual membership or give a one-time contribution, we’ll give a membership to someone who can’t afford access. It’s a simple way for you ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published ...

Over the past several decades, the lack of reproducibility in biomedical research has become increasingly concerning, particularly in the drug development process. The study of science has undergone a ...

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 ...

In 2012, psychologists Will Gervais and Ara Norenzayan published a paper in the journal Science reporting a series of experiments that suggested engaging in analytical thinking could reduce someone’s ...

Unlike nuclear DNA, mitochondrial DNA (mtDNA) is circular in nature and organized as mitochondrial nucleoids comprised of DNA-protein complexes that are distributed in the matrix. It is also inherited ...

The replication crisis in psychology refers to concerns about the credibility of findings in psychological science. The term, which originated in the early 2010s, denotes that findings in behavioral ...
