Answer #1


• 16S ribosomal RNA (or 16S rRNA) is the component of the 30S small subunit of a prokaryotic ribosome.


• Role of 16s rRNA in bacterial translation.
-16s rRNA has a important role in initiation of translation in prokaryotes.
-The 3' end of 16s rRNA complexes with an initiating signal site on m-RNA and helps in position the m-RNA on ribosome.(The 3' end contains the anti-Shine-Dalgarno sequence, which binds upstream to the AUG start codon on the mRNA).
-16s rRNA binds initiation factor-3 and helps in initiation of prokaryotic translation.

• 16s rRNA used for classification of bacteria
- 16s rRNA is a highly conserved structure in bacteria. That means it has obtained very less mutations over the years.
-Thus, it is due to this evolutionary conserved nature of 16s rRNA, it has found use as a marker for the classification of bacteria.

• Structural Roles of 16s rRNA
-It has a structural role, acting as a scaffold maintaining the positions of the ribosomal proteins.

    In the protocol we followed, 16S rRNA gene segments were amplified by PCR, then individually ligated into a vector, transformed and propagated in bacteria, and 9 bacterial “clones” sequenced by the Sanger method. Each clone had a unique sequence we subsequently compared. If we had used an Illumina Next Generation Sequencing method, would the “cloning” of individual fragments have been necessary?

    Bacteria in the genus Rhizobium and in the genus Bartonella are believed to have come from the same common ancestor based on 16S rRNA and they are grouped in the same order (Rhizobiales). However, bacteria in the rhizobium group but not Bartonella can convert nitrogen from the air to ammonia even though both of them came from the same ancestor. How is this possible and what could have happened to bacteria in the group rhizobium to enable it to convert...

    Once a bacterial 16s rRNA gene has been amplified, it is possible to have the nucleotide sequence of the DNA determined. There are many different techniques for this. In lab, you isolated and amplified DNA from a known organism (Escherichia coli), but what if you had to identify an unknown organism? You would send the sample away for sequencing and then once you got the results you would “BLAST” the sequence. Using the Standard Nucleotide BLAST on NCBI and the...
