Would like to ask you a question is that I saw such a passage in the literature "the CSB gene length range is 1468-1530 bp, MC58 the CSB gene length is 678 bp, the product of 1-644 bases the CSB gene encoding is enough to exercise the function of the gene" want to ask someone who knows all the words of how to determine "the product of 1-644 bases the CSB gene encoding is enough to exercise the function of the gene"? Thank you for the
