||P.2/21 bottom paragraph:"Additionally the fact that rRNA are in multiple copies enhances replication-linked gene dosage effect. For example, Escherichia coli bears 7 rRNA copies, therefore in exponential phase their copy number can go from 7 to 28 while RP [ribosomal protein] and RNAP which are in single copy can go from 1 to as most 4 copies. On the other hand, gene expression can vary by 300-fold according to its genomic location, an
amount that is not explained by gene dosage effects but rather by the presence of overlapping chromosome structural organization features [primary sources 8, 25]." P.13/21 top paragraph:"A recent publication reported 300-fold expression changes of gfp according to its genomic site of insertion in slow growing conditions [primary source 25]. Such variation in expression cannot be accounted by gene dosage effects but rather the presence of overlapping chromosome structural organization features."
