“Transcription termination. RNA polymerase will keep transcribing until it gets signals to stop. The process of ending transcription is called termination, and it happens once the polymerase transcribes a sequence of DNA known as a terminator.”
In Eukaryotes, maturation if the RNA into mRNA by slicing, caping and poly-adenylation. The mature mRNA is transferred to cytoplasm to be translated into proteins by ribosomes. In Prokaryotes, translation and transcription occur simultaneously.
Pleiotropy is a condition that occurs when one gene affect several other phenotypic traits that are not related. The autosomal dominant allele of the genetic disease called blue sclera, is pleiotropic. It has the potential of causing also fragile bones and deafness which are entirely unrelated traits. Genetic mutation of a gene is the most likely explainable reason for the connection of these traits together.
