True or False Due to developed molecular tools functional ge

True or False:

Due to developed molecular tools, functional genes can be identified directly in the clinical and environmental samples.

Solution

True because the functional genes can be directly identified in samples by the metagenomic arrays, using special biomarkers characterized by a unique order for the specific gene or gene sequence, SNPs etc and their molecular structures. This biomarker array is sometimes followed by the amplification tool and sequencing method for the entire DNA or RNA extracted from the sample.
