Length of an RNA chain in a simple bacterium?
Does anyone know the length of the RNA chain (in terms of number of bases) in bacterial DNA?
I want to do a calculation of how many tries it would take a theoretical monkey to stick them together to achieve a viable chain.
Answers:
? Your question doesn't make much sense.
The length of a DNA chain in a bacterial chromosome depends on the bacterium for E.coli it is approximately 4.7 million bases.
Have a look at :

for different bacteria
The length of an RNA transcript varies. If an average protein has 200-300 amino acids then the coding region should be 600-900 bases. You'll need some non-coding bases in RNA (ribosome binding site, termination etc) so to be on the safe side add 100 more bases. Thus you would have 700-1000 bases in an average monocistronic mRNA-bacteria usually have genes in operons and thus a RNA transcript usually will have the sequence for more than one proteins.
Not quite sure what you mean. Are you looking the the total length of the genomic DNA or the length of an RNA transcript?
If it's the length of the DNA, it differs by organism, but remember that non-genomic DNA in the form of plasmids are also functional and quite stable in bacteria so the monkeys wouldn't need to create a whole genome.
As for RNA length, this obviously varies by gene transcript. Some are small, some are large depending on the protein that is encoded.
If you want to look up a few DNA (or cDNA if you are interested in the transcript sequence) have a look at the NCBI website and do a "neucleotide" search (http://www.ncbi.nlm.nih.gov ).
To get you started here is the first 20th of the compete genome for Yersinia pestis strain CO92 (FASTA formatted for convienience).http://www.ncbi.nlm.nih.gov/entrez/viewe.
. enjoy :-)
No idea. it really depends i guess on the species and all, the genomes size would reflect directly on the amount of DNA but let's not forget bout plasmids which might differ a lot between colonies. Why directly the amount of RNA = genome size. Because there is no post trancription splicing og the mRNA strand; thus for bacterium don't bother bout the difference between cDNA and stuff. Bacterium being simple; just find out the size of the genomic DNA
