DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold ...

Researchers at The Institute of Cancer Research, London, have uncovered how the DNA repair enzyme XPF-ERCC1 is recruited to sites of damage and activated inside cells, resolving a long-standing ...

Here are strategic revision techniques, important topics, diagram practice, and exam-day strategies to help CBSE Class 12 ...

In 1869, Swiss scientist Friedrich Miescher isolated a mysterious substance from cell nuclei—an overlooked finding that would ...

DNA is often described as the instruction manual for building the fundamental components of life. Proteins are helpers that ...

Making diagrams saves time, reduces ambiguity, and leaves a memorable impression on examiners. Check tips shared by the ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

The discovery of catalytic RNA transformed our understanding of life's beginnings. Clare Sansom explores how the RNA world ...

Unrepaired DNA-protein crosslinks (DPCs) – highly toxic tangles of protein and DNA – cause a process that leads to premature ...

T ermites are the descendants of cockroaches, and have undergone significant genetic change to live in vast colonies where breeding is restricted to a single pair. A study of the genetic path they ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a cell divides – which they need to do constantly. Without this process, we ...
