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 ...

Labels, particularly when applied to human beings and their behavior, can have a surprisingly polarizing effect, regardless of the label’s efficacy. Some people resist labels altogether, while others ...

The appetite for food made with the use of gene technologies will be tested in New Zealand, amid ongoing regulatory reform and an easing of food labelling requirements. Food Standards Australia New ...

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 ...

Stacey Leasca is an award-winning journalist with nearly two decades of newsroom experience. She is also the co-founder of Be a Travel Writer, an online course for the next generation of travel ...

The FDA is delaying implementation of a rule that would require food companies to print nutritional information on the front labels of their products. The proposed rule was developed by President ...

This valuable descriptive manuscript builds on prior research showing that the elimination of Origin Recognition Complex (ORC) subunits does not halt DNA replication. The authors obtain solid data ...

The discovery of DNA ligase by the Gellert, Lehman, Richardson, and Hurwitz teams in 1967 was a breakthrough in molecular biology. These essential enzymes maintain genome integrity and play a vital ...

Movie 1: Movement of single nucleosomes in living human cells. The movie shows nucleosome fluctuations in euchromatin (left), where gene expression is active, and in heterochromatin (right), where ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

Researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer. Every day, billions of cells in your body ...

MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...
