14
SSH begins with the isolation of RNA (or DNA) from two different sources or conditions of interest.
sample preparation
15
During this process, the samples are layered on top of a heavy isotope solution and centrifuged. As the centrifuge spins, molecules with different densities will separate along the gradient.
density gradient centrifugation
16
It involves manipulation of molecules like RNA, DNA and PROTEINS
molecular biology
17
It is a molecular biology technique used to selectively enrich and identify differentially expressed genes between two distinct RNA populations, typically representing a "tester" sample and a "driver" sample.
suppressive subtraction hybridization
18
Complementary DNA (cDNA) is synthesized from the RNA in both the tester and driver populations.

23
Microorganisms in the environment take up and metabolize the isotopically labeled compound if it is a source of nutrients or energy for them.
microbial uptake
24
can be done using reverse transcription, and each cDNA population is labeled with different adaptors or linkers.
cdna synthesis
25
The tester cDNA is divided into two parts. One part is left unmodified, while the other part is subjected to a suppression step, where it is made less abundant by hybridizing it with an excess of driver cDNA.
