What are enzymes? Ø All living organisms in the world should possess TWO fundamental properties Ø They are: (1). Must be able to self-replicate (2). Must be able to catalyze chemical reactions efficiently and selectively Ø Enzymes are the molecules which enables each living […]
What is Nucleotide Excision Repair (NER)? As the name suggests it is a type of DNA repair mechanism. In nucleotide excision repair or NER, the damaged base along with a short stretch of healthy strand is removed and later the gap is refilled with correct nucleotides. Thus the NER pathway […]
Cancer is a disease of the genome. And that’s what happens. You make mistakes in a cell somewhere in your body that causes it to start to grow when it should’ve stopped, and that’s cancer. And those mistakes are mistakes of DNA. Francis Collins What is Base Excision Repair or BER? […]
Science is beautiful when it makes simple explanations of phenomena or connections between different observations. Stephen W. Hawking, 2011 What is Photoreactivation? Photoreactivation is a type of DNA repair mechanism present in prokaryotes, archaea and in many eukaryotes. It is the recovery of ultraviolet irradiated damages of DNA by visible […]
“Genetic variation is important for evolution, but the survival of the individuals demand genetic stability” DNA is the genetic information carrier molecule in the cell and thus it is very essential to keep the genetic information intact. Even though DNA holds a prime position, it is one of the highly […]
