Here we show that the Methanosarcina mazei PylRS (MmPylRS) can be evolved to efficiently charge a Uaa with a short aromatic side chain, in contrast to the long aliphatic side chain of the native substrate Pyl.
"Cells have been evolving to exploit this apparently chaotic organization to efficiently store the genetic information and use it for their function," says Marco Di Stefano, a biophysicist now at the National Centre for Genomic Analysis in Barcelona, Spain.
It's evolved to separates, or dresses.
It is likely that Bangladeshi H9N2 viruses are evolving to adapt and replicate efficiently in the poultry host because genes mostly comprising the nucleoprotein complex (NP, PA and PB1) are the most heterogeneous.
Since T cells can only recognize processed antigen in the context of the MHC, it may be that B. anthracis has evolved to efficiently impair the adaptive immunity by attacking DCs, which are fewer than 3% of the white blood cells in the spleen/blood, rather than attacking T cells directly.
We may have evolved to efficiently store fat for times of famine, says Veech, but we also evolved ketosis to efficiently live off that fat when necessary.
Over the years, a number of strategies have evolved to efficiently decellularize tissues and more recently whole organs.
Adaptive action suggests that the brain of the receiver has co-evolved to efficiently decode expression signals.
As the variant surface glycoprotein (VSG) represents ∼90% of trypanosome plasma membrane protein, it is possible that VSG has evolved to fold efficiently to minimize ER folding burden.
We are not evolved to digest it".
