In nucleotide excision repair, the damaged nucleotide (s) are removed along with a surrounding patch of DNA. In this process, a helicase (DNA-opening enzyme) cranks open the DNA to form a bubble, and …

The video also distinguishes between mutations and DNA damage, and explores both endogenous and exogenous factors that can cause DNA damage. Finally, it discusses the process of nucleotide …

When mistakes occur, the mismatch repair mechanism steps in post-replication to fix errors, preventing mutations and maintaining DNA integrity. Created by Efrat Bruck.

W naprawie przez wycinanie nukleotydu (NER, ang. nucleotide-excision repair), tak jak i w naprawie źle sparowanych zasad DNA (MMR), którą widzieliśmy powyżej, usuwany jest odcinek zasad.

Nonsense Mutation: A change in the nucleotide that converts a codon into a stop codon, leading to premature termination of protein synthesis. This often produces a nonfunctional protein, particularly if …

Formation and repair of tobacco carcinogen-derived bulky DNA adducts (Formación y reparación de aductos voluminoso del ADN derivados de carcinógenos del tabaco).

Is a mutation like a mistake in the DNA? In my bio class they said that mistakes in translating DNA were very rare like 1 in a billion, so is a mutation like this or is it different? Also how can an extra …
