Video contains Steps of DNA repair mechanism - 00:44 minutes Types of DNA repair - 01:25 minutes DNA Damage and DNA repair types - 01:56 minutes Mismatch Repair - 03:23 minutes Hereditary NonPolyposis Colon Cancer or Lynch Syndrome - 5:25 minutes Base Excision Repair - 06:36 minutes Nucleotide Excision Repair - 09:46 minutes Xeroderma Pigmentosum : 12:44 minutes Cockyane Syndrome - 13:47 minutes Direct Repair Pathway - 14:28 minutes Homologous Recombination and Non Homologous End Joining - 16:48 minutes DNA Double Strand Break Repair - 16:48 minutes Ataxia Telangiectasia - 20:47 minutes NEET PG Biochemistry MCQs - 21:41 minutes Types of DNA Repair - Mismatch repair Base excision repair Nucleotide excision repair Direct repair Homologous recombination and Non-homologous end-joining repair The mechanisms used for the repair of DNA involve: First recognition of distorted region of the DNA. Secondly removal or excision of the damaged region of the DNA strands. Then filling of gap left by the excision of the damaged DNA by DNA polymerase. Finally sealing the nick in the strand that has undergone repair by a ligase #DNArepair #xerodermapigmenosum #biochemistrybasicsbydramit #NEETPG #NEETPGbiochemistry #USMLE #dnadamage
