Ribosomes producing proteins, but need proteins to be produced?

Ribosomes are the only means we know by which cells produce proteins. Consequently, all proteins are made by a ribosome, including the proteins that then become part of a new ribosome. It's never a ...

what is the princlple of using DMS (Dimethylsulphate) for structural analysis of rRNA?

Here is a good explanation of the theory and chemistry behind DMS footprinting, from chapter 11 of Probing RNA structure within living cells : In vivo chemical probing assay using dimethyl sulfate (...

Where can I obtain the sequence of the E. coli ribosomal RNA precursor?

Generally most organisms have multiple copies of the genes/regions coding for ribosomal RNA (since it's needed quite a lot). Additionally these regions can be repetitive or otherwise similar to ...

How is 16s rRNA used to identify unknown bacteria?

It is not conserved, its sequence is not the same in all bacteria. Indeed, it has a slow rate of evolution (mutation) that make it perfect to build phylogenetic trees. As correctly suggested by David ...

16S sequencing: pooled or individual samples?

Ultimately, it depends on what insights you are trying to glean from your sequencing data, but from a purely scientific perspective, there's almost never a reason to pool samples in the the way you ...
