How Do Enzymes Repair DNA So Precisely? - Biology For Everyone
How Do Enzymes Repair DNA So Precisely? Have you ever wondered how cells repair their DNA with such remarkable accuracy? In this informative video, we'll explain the processes and enzymes involved in DNA repair mechanisms. We’ll start by describing how DNA copying during cell division is protected by specialized enzymes that double-check each nucleotide for errors. We’ll discuss how these enzymes correct mistakes immediately, preventing mutations from occurring. Next, we’ll explore additional repair systems that scan the entire genome for mismatched bases, and how they distinguish between original and newly synthesized strands to ensure precise correction. We’ll also explain how cells fix damage caused by ultraviolet light or chemicals through nucleotide excision repair, removing damaged sections and replacing them with correct sequences. Furthermore, we’ll cover base excision repair, a process where specific enzymes identify and remove damaged bases, filling in gaps with accurate DNA. The most serious damage—double-stranded breaks—are repaired through homologous recombination, using intact sister chromatids as templates to restore the original sequence perfectly. We’ll highlight how enzymes recognize specific chemical features of damaged DNA, ensuring only affected areas are targeted. Lastly, we’ll discuss how these enzymes utilize energy from nucleotide hydrolysis to perform rapid, precise repairs, maintaining the integrity of our genetic information.
