E. coli K-12 codon bias and tRNA numbers
Description
A list with elements trna
, a vector of length 64 of tRNA gene copy numbers
in the Escherichia coli K-12 genome, w
, a data frame with some codon bias
statistics for 49 E. coli K-12 coding genes, and m
, a 49 by 61 matrix of
codon frequencies for the 49 genes in question.
Usage
