pressures in the evolution of protein-coding genes‚ the nonsynonymous and synonymous substitution rate ratio (KA/KS) and the radical and conservative amino acid replacement rate ratio (KR/KC). Because the KR/KC ratio depends on the definition of radical and conservative changes in the classification of amino acids‚ we develop an amino acid classification that maximizes the correlation between KA/KS and KR/KC. An analysis of 3‚375 orthologous gene groups among 5 mammalian species shows that our classification

What do Kingda Ka and the discoverer of radioactivity‚ Marie Curie‚ have in common? Actually‚ there is a lot more than you would think. You might say to yourself that they are completely different‚ which is correct‚ yet incorrect. One thing is a rollercoaster and the other is a famous scientist‚ but when you look past just their physical descriptions‚ you will see how much they actually are alike. They both follow similar paths and they both faced many hardships‚ but also many great things. Firstly
