WebMar 27, 2024 · To start, PCR stands for a laboratory technique known as polymerase chain reaction. In this test, the goal is to selectively amplify trace amounts of genetic material, identifying specific parts of DNA. Just as a reminder, DNA is the genetic code that is present in every cell in the body. WebWe aim to discern specifically where and when lncRNA NTAB_LNC014148.1 is expressed in N. tabacum seeds using RT-PCR as a first step in the characterization of this particular lncRNA. DNA: RNA interaction assays will be utilized to confirm interaction among lncRNA and predicted gene regions to further characterize lncRNA cellular function.
