Quality control of genetic material is a function conserved in all living organisms. DNA suffers from many environmental stresses, including attacks by reactive oxygen species, radiation, UV light ...

Here we present the X-ray structure of a hexameric LTag with DNA helicase activity. The structure identifies the p53-binding surface and reveals the structural basis of hexamerization.

This study reveals how SV40 helicase unwinds DNA, highlighting ATP hydrolysis's role in translocation and offering insights ...

DNA is the foundation of all organisms and is responsible for development, function, growth and reproduction. Let's break down some biology and learn more about this nucleic acid and what it does.

Revise the structure and replication of DNA for your Higher biology exam with Bitesize Scotland interactive practice quizzes covering feedback and common errors.

Base Pairing: The two strands of DNA are held together by hydrogen bonds between the nitrogenous bases. Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C). This ...

Thymine (T) is one of the four nucleobases found in DNA, alongside adenine (A), guanine (G), and cytosine (C). It is a pyrimidine derivative, meaning it has a single-ring structure. Thymine plays a ...

Swapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study. The study -- conducted using E ...

Computational and experimental studies show synonymous mutations that change the DNA sequence of ... illustration of how kinetics can also control protein structure and function,” said Ed O ...
