The origin of the eukaryotic photosynthesis if the photosynthetic organelle of a protist is discovered to be most closely related to a different cyanobacterium than the one that gave rise to plastids. Introduction: Endosymbiosis is a hypothesis that explains the evolution of the eukaryotic cells like mitochondria in animal and fungi and chloroplast in plants from the prokaryotes. The mitochondria and chloroplast show similarities to the bacterial cells. The eukaryotes are called as “combination” organisms because their DNA shows that some of their cellular character and genes are derived from archaebacteria and some other bacteria. This occurred due to a symbiotic relationship process known as endosymbiosis. In this association, one organism lives inside the other.

a) The lux operon is under positive control. Based on this information, does the luxR regulator sequence make a repressor protein or an activator protein? b) How will binding of this complex affect RNA polymerase? Remember this operon is under positive control. c) AHL is a signal molecule that V. fisheri makes to communicate with neighboring bacterial cells. This molecule can diffuse outside of the cell and into another bacterial cell in close proximity. This type of communication between bacterial cells is known as quorum sensing. If bacterial cell density is low how will this affect the lux operon? What will happen if the density is high?

1) Given an mRNA with the following sequence, please translate the codons to a chain of amino acids. Use the codon chart below.5’AUG/CCU/GCU/UAC/CGG/GAG/UAA3’ “met-_________-_________-_________-_________-_________”STOP” 2) Assuming the original polypeptide chain below, match each type of point mutation with the polypeptide chain that results. Original polypeptide: Pro-Thr-Ser-Leu-Leu-His-Asn A. Missense B. Silent C. Nonsense D. Frameshift ______ Pro-Thr-Ser-STOP ______ Pro-Thr-Ser-Leu-Ile-His-Asn ______ Pro-Thr-Ser-Leu-Leu-His-Asn _______ Pro-Thr-His-Cys-Tyr-Thr
