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 ...
Mitochondrial transcription elongation factor maintains the balance between transcription and replication of mitochondrial DNA offering insights into potential treatments for mitochondrial disease and ...
Structural biologists at the University of Wisconsin-Madison today published cryo-electron microscopy structures of the complete bacterial DNA replication restart complex — a molecular machine that le ...
Bacterial DNA replication is a highly coordinated process that ensures faithful genome duplication and cell division. Replication initiates at a single chromosomal origin (oriC) where multiple copies ...
The molecular choreography of DNA replication is a finely balanced process ensuring that genetic information is faithfully transmitted during cell division. Replication initiation begins with origin ...
Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...
CDT1 inhibits the helicase activity of the MCM complex, thereby suppressing nascent strand synthesis in DNA replication in cultured human cells. This action results in fork collapse and DNA damage, ...
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 ...
Not all DNA looks like the familiar double helix. Sometimes, parts of our genetic code fold into unusual shapes under certain conditions. One such structure known as a G-quadruplex (G4) looks like a ...

DNA replication made simple for bio students
From the first unzip of the double helix to the final joining of DNA fragments, replication is a carefully coordinated process. Understanding it helps explain how life preserves its genetic code with ...
Researchers at MD Anderson have identified RNase H2 as a key survival mechanism in triple-negative breast cancer, helping ...

Cancer’s most notorious protein MYC also quietly repairs tumor DNA damage — blocking the trick could make chemotherapy far deadlier to cells it targets
For decades, oncologists have watched a frustrating pattern repeat itself. Tumors fueled by the MYC protein, one of the most ...
