I'm guessing "molecular methods" here means using bacterial ribosomal RNA to classify bacteria.

Basically, bacteria used to be classed as one big group, but now due to this kind of molecular analysis, its been found that a subset of bacteria, the archaea, are more similar to eukaryotic cells (whereas the eubacteria are more like the traditional "bacteria").
Molecular sequencing has highlighted this extra subdivision, and has shown that bacterial divisions differ quite a bit from an evolutionary perspective. You wouldn't really be able to see this difference using the cells' features to classify them, hence the importance of molecular methods.

Hope that helps! ...and that I've not made things worse!!

So when you say using bacterial ribosomal RNA, are you referring to the process called Ribotyping?

Also would other approaches like DNANA hybridization and fatty acid analysis be used in the classification of BACTERIA? Your help would be very appreciated. Look forward to your reply. Thanks
