Eukaryotic DNA replication begins with recruitment of the ring helicase MCM2-7 by the origin recognition complex (ORC) in a reaction facilitated by initiation factors Cdc6 and Cdt1. A new cryo-EM ...

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 ...

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.

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 ...

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

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 ...

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 ...
