This seems to me to be two independent pieces of data. mRNA seq allows one (in case of linear amplification) to quantify message RNA transcripts of genes of interest. that is, how many copies of mRNA for given gene are in the cell at the moment. It is ultimately, how active this gene is. In neurons different genes will be more active, than in epithelial ...

There are some databases in which you can search for E.coli gene expression data: GenExpDB: E. coli Gene Expression Database Many Microbe Microarrays Database (M3D): A resource of microbial gene expression data Stanford MicroArray Database (use the search tool to find relevant organisms) Colombos (COLlection Of Microarrays for Bacterial OrganismS) ...

In RNA sequencing, total RNA is extracted, then mRNAs are purified out from the sample using polyT columns (since mRNAs have a polyA tail, this will attach to a polyT DNA chunk that is attached to some solid surface). This step is necessary because ribosomal RNAs are much more abundant than mRNAs, and for sequencing you only want to use mRNAs. Then the ...
