Regulation of Gene Expression in Eukaryotes In eukaryotes, the Central Dogma of Genetics can be expanded to include post-transcriptional processing and post-translational processing, thus the Dogma becomes: Replication - Transcription Post-transcriptional Processing -Translation - Post-translational Processing - Functional Protein - Expressed Trait. This is the flow of information from the genetic material to the actual physical, chemical or behavioral trait in an organism. Of course, some traits are controlled by multiple genes and some also have an environmental component. At...

This short RNA (miRNA) is found in eukaryotic cells. miRNAs are post-transcriptional regulators that bind to complementary sequences on target mRNAs, resulting in enhancement of mRNA degradation by nucleases and/or _________. For the study of gene functions, artificial introduction of miRNA (siRNA) is performed to cells or animals. This experimental technique is called gene silencing and or _________, compared to the gene-deleting transgenic techniques. Select one: a. transcriptional repression ;;;; Knock-Down b. translational repression ;;;; Knock-Down c. transcriptional repression ;;;;...
