End-use wise, pharmaceutical and biotechnology firms are estimated to be the largest segment owing to the presence of substantial number of biopharma entities that have adopted rDNA products.
Fish analysis with the distinct 18S-25S rDNA probes demonstrated comparable patterns considering the number and position of loci, which denoted that each locus is composed by the entire ribosomal unit.
isolates were confirmed All the ITS rDNA sequences of isolates were confirmed as Colletotrichum gloeosporioides, Colletotrichum acutatum and Fusarium oxysporum.
The amplicon frequency values, while not linearly representative of the true frequency of the occurrence of each underlying bacterial species type in the sample (due to issues such as different numbers of rDNA copies per genome of different bacterial species, or sequence-based differences in PCR amplification kinetics), can be corrected back by bioinformatic processes to yield meaningful numbers on the relative frequencies of each bacterial species identified in the sample.

The concomitant use of 18S and 5S rDNA probes, using the FISH technique, showed the 18S ribosomal cistrons in a pair of subtelocentric chromosomes, on the long arm in the terminal position (Figure 1b) and the 5S sites were found in another subtelocentric pair, on the long arm in the interstitial region, near the centromere (Figure 1b).
rhinoscleromatis was tested in silico through gene pattern prediction of 759 bp and 311 bp of a sequence rDNA 16S gene with Sal I restriction enzyme (Figure 2A); nevertheless, due to polymorphism described among the ADNr 16S gene for K.
