Lipid Bilayer

Lipids in cells have three main functions: energy storage, signal transduction and forming the matrix of biological membranes. Lipid membrane have asymmetric distribution of lipids between two leaflets. Cell membrane composed of polar lipids that self assemble to form bilayer. Thus, cell membrane forms asymmetric structure which means two sides of membrane are functionally and […]

Heterochromatin and Euchromatin

Heterochromatin and euchromatin are two types of chromatin structure. Heterochromatin is defined as densely packed chromatin and euchromatin is defined as loosely packed chromatin. The condensed chromatin structure indicates inactive transcription. This is heterochromatin structure. Methylation stop the gene expression as it blocks the promoter site from binding to transcription factors. Therefore, it indicates inactive […]

Advantages of biodiversity

  Overview: Diversity in biology is defined as the number of species or organisms in an environment. Advantages of diversity: 1. More biological diversity means more niches and roles are played by each organisms that helps to balance the ecosystem. For example: more species diversity results in healthy ecosystems as it can recover from various […]
