We also evaluated how mutating individual amino acids could change the interaction.” Researchers have deployed a number of computational methods to examine the spike-ACE2 interaction. The ab initio ...

Scientists have discovered that some tiny segments of RNA thought to be junk instead have a functional role in suppressing production of certain messenger RNAs and appear to help cells respond to ...

The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. The three-dimensional shape of a ...

For example, the molecular clock theory (Zuckerkandl & Pauling 1962) predicts an increase in fixed amino acid mutations of protein ... Under this model, fixed DNA nucleotide mutations that do ...
