WebSubstitution matrices (such as BLOSUM matrices) can be used to add evolutionary distance weighting these scores. Figure 14 Representation of a scoring matrix based on a multiple … The molecular clock hypothesis predicts that the rate of amino acid substitution in a particular protein will be approximately constant over time, though this rate may vary between protein families. This suggests that the number of mutations per amino acid in a protein increases approximately linearly with time. Determining the time at which two proteins diverged is an important task in phylogenetics. Fossil …
