Halophilic proteins have greater abundance of acidic over basic and very low bulky hydrophobic residues. Classical electrostatic stabilization was suggested as the key determinant for halophilic adaptation protein. However, contribution specific interactions (i.e. salt-bridges) to overall stability is yet be understood. To understand this, we use Adaptive-Poison-Boltzmann-Solver Methods along with our home-built automation workout net well associated component energy terms such desolvation...

Most viruses–including SARS-CoV-2, seem to have evolved over time. The lack of stringent proofreading mechanisms makes viral DNA/RNA replication error-prone. When a virus replicates, it sometimes changes little bit, which is called mutations. Any with one or more new mutations can be referred as “variant” the original virus. last 2 years witnessed emergence large number variants. Since pandemic’s beginning, SARS-CoV-2 coronavirus has mutated extensively, resulting in different variants One...

Abstract Nature and nurture have always been a prerogative of evolutionary biologists. The environment’s role in shaping an organism’s phenotype has intrigued us. Since the inception humankind, twinning existed with unsettled parley on contribution nature (i.e. genetics) versus environment), which can influence phenotypes. study twins measures genetic that environmental for particular trait, acting as catalyst, fine-tuning phenotypic trajectories. This is further evident because number human...
