How much DNA RNA and protein are in an E. coli?

In: Microbiology, Genetics [Edit categories]

Answer:

There is approximately 100-155 fg/cell of protein and ~20 fg/cell of RNA based on Cox, R.A. (2004) Quantitative relationships for specific growth ratios and macromolecular compositions of Mycobacterium tuberculosis, Streptomyces coelicolor A3(2) and Escherichia coli B/r: an integrative theoretical approach. Microbiology. 150:1413-26.

As a side, there is also ~4.2 fg/cell of DNA based on Kubitschek, HE and Friedman, MC (1971) Chromosome replication and the division cycle of Escherichia coli B/r. Journal of Bacteriology. 107:95-99.

What is the correct order dna-RNA-protein or dna-protein-RNA or RNA-protein-dna?
It's DNA - RNA - protein. DNA encoding a gene is transcribed to mRNA or messenger RNA by RNA polymerase. The RNA is then translated into a protein sequences at the ribosome. tRNA's or transfer RNA's...
