natta225 [31]

Answer:

■Gene sequences would be used to make Probes for both the Southern and Northern blots.

■The probes will be used to view the presence of each gene with the use of isolated genomic DNA obtained from the isolated bacterium

■Each probes hybridized to the genome shows the pathway is isolated and point of the genes were involved in the substrate catabolism

■The carbon source in the isolate is derived from the substrate inducing the catabolic pathway as RNA determine transcripts present

■Probes hybridizing to the same sequences would be used to determine the gene activity for the pathway as seen in the southern one

■since all the genes present in the genome couldn't be identified, the northern would be important to work on

■Catabolic pathway is determined by the same genes. Hence, the need for gene/transcript probes to hybridize to the transcriptome.
