Trimethylated Lysine 4 At Histone 3 Shows The Same Circadian Rhythm At Promoters Of Diversely-Expressed Genes In Chlamydomonas Reinhardtii, Robyn M. Wilson

Masters Theses & Specialist Projects

Circadian clocks are biochemical mechanisms that allow eukaryotic and some prokaryotic organisms to coordinate their physiology with daily environmental changes. It enables organisms to increase their fitness by taking advantage of beneficial environmental conditions while also avoiding or restricting certain sensitive processes during harsh conditions. Similarly, post-translational histone modifications allow eukaryotic organisms to regulate gene expression in response to environmental or developmental factors. Some post-translational modifications of histones are associated with active transcription while others are associated with repressed transcription depending upon the location, type and degree of modification. Trimethylation of lysine 4 on the N-terminal tail of histone H3 …
