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 ...

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 ...

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 ...

The Medical College Admission Test (MCAT) is a crucial and challenging exam that medical school applicants must take. It tests the knowledge, skills, and problem-solving abilities that are essential ...

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 ...

A new study has identified USP50, a protein that helps regulate enzymes during DNA replication, ensuring proper use of nucleases and helicases. The discovery sheds light on how cells manage ...

Thorin — nicknamed after a dwarf in J. R. R. Tolkien's "The Hobbit" — is also called the "last Neanderthal" because he may have lived as recently as 42,000 years ago. When you purchase through links ...

Newly discovered DNA could shed light on one of Italy's most famous cold cases, finally revealing the "Monster of Florence" serial killer who murdered young couples in the 1970s and 80s. More than ...

Around 2% of the genomes of modern Eurasians contains Neanderthal DNA. Here's how it affects our health. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...
