Transposable elements I. What is a transposable element?
... A. Any segment of DNA that can move from place to place in the genome 2. a few are beneficial to host: eg. In flies they lengthen chromosome ends without telomeres II. Where are transposons found? A. Found almost everywhere 1. viruses, bacteria, fungi, plants, animals B. major constituents of genome ...

trp operon – a repressible system
... Gene regulation in eukaryotes is more complex than it is in prokaryotes because of: – the larger amount of DNA – the organization of chromatin – larger number of chromosomes – spatial separation of transcription and translation – mRNA processing – RNA stability – cellular differentiation in eukar ...

Gene Regulation
... Gene Regulation Some genes are regulated (turned off and on) by repressor proteins While others use proteins that enhance the rate of transcription. Operons are generally not found in Eukaryotes. Gene regulation is controlled individually and have regulatory sequences that are much more complex that ...

TRANSPONSONS or TRANSPOSABLE ELEMENTS
... These are some notes taken whilst view the PowerPoint presentation and some may be of assistance in filling the gaps. Barbara McLintock (1940s) was the founder of “jumping genes” which led to the discovery of transposable elements (TE). She suggested that genes could change loci and produce phenotyp ...
