allScores$($geneList$1,$geneList$2)$: Your first step is to write a function to obtain the alignment score between

all proteins in two species. allScores takes as input two lists of genes. It then takes every protein in the first list

and calls memoAlignScore on it with every protein in the second list. $($Remember that the protein sequence for

each gene can be obtained from geneD$).$ In memoAlignScore you can use the blosum$62$ substitution matrix $($which

you have already imported at the top of your file$)$ and a gap penalty of $-9$
