Two Types of Apoptosis In the previous post, we have discussed the characteristic features and significance of programmed cell death or apoptosis. As we discussed, the stimuli for the execution of programmed cell death can be of internal or external to the apoptotic cell. Based on the source of stimuli, […]

Apoptosis: The Molecular Mechanism of Programmed Cell Death (Short Notes)
What is Apoptosis? Why apoptosis is known as the ‘Programmed Cell Death’? The total number of cells in an organ or organism is fundamentally fixed to a specific range in all multicellular organisms. In every multi-cellular organism, the cell number is effectively controlled by two strategies- (a) by regulating cell […]

Different Types of DNA Conformations DNA, the genetic information carrier molecule of the cell, is a long polymer of nucleotides and can adopt different types of structural conformations. The various types of conformations that the DNA can adopt depend on different factors such as: 1. Hydration level 2. Salt concentration […]

Apoptosis vs Necrosis Apoptosis and Necrosis Apoptosis and Necrosis are two types of cell death occur in organisms. The cells undergo death when the cell death becomes necessary as a part of developmental process or they fail to adapt to injuries. Both these types of cell deaths differ in their […]

Does the DNA really need to FOLD inside the nucleus? A diploid human cell contains approximately 6.4 billion base pairs. These 6.4 billion base pairs are distributed in our 23 pairs (2n = 46) of chromosomes. We know that each chromosome contain a single linear segment of DNA. According to Watson […]
