Course Description - Prokaryotic and Eukaryotic Protein Synthesis Aims A number of biological situations are controlled at the “post-transcriptional” level and much of this through the regulation of translation, either globally or for specific mRNAs. This course will provide the basic mechanistic description of protein synthesis and several examples of how protein synthesis may be regulated in global, specific or auto-regulatory manner. Contents The introductory lectures will present information on the components of translation (aminoacyl- tRNAs, mRNAs, ribosomes) and the protein factors that facilitate their use. Important differences between eukaryotes and prokaryotes will be stressed. The papers chosen by Dr. Merrick will illustrate specific methods used in the study of protein synthesis, the concept of controls, both positive and negative, and model interpretations based upon the results presented. The papers chosen by the students will provide the student with the opportunity to present to the class their interpretation of why a particular series of experiments was performed, what were the methods and whether the authors conclusions are valid. Prerequisites A course in general biochemistry, which would include simple enzyme kinetics, and general molecular biology (DNA makes RNA makes protein). Types of teaching 14 hours of lecture by Dr. Merrick, 5 hours on how to read the literature by Dr. Merrick, approximately 10-12 hours of presentation by the students (see the lesson plan). Students will present a current literature paper of their choice, but in the field of translation. At the time of the presentation, the students should turn in to Dr. Merrick a three-page paper on what the next series of experiments should be to extend this research. Subsequently, Dr. Merrick will provide individual feedback to the students. Compulsory Program Presentation of research papers by Dr. Merrick and the students.

See Lesson Plan next page Lesson Plan for the graduate course "Prokaryotic and Eukaryotic Protein Synthesis" Each numbered session is for 1 hour. 1. Introduction to protein synthesis 2.

Selenocysteine and Pyrrolysine, the 21st and 22nd amino acids 15. Introduction to the literature 16. Papers presented by Dr. Merrick – 1 17. Papers presented by Dr. Merrick – 2 18. Papers presented by Dr. Merrick – 3 19. Papers presented by Dr. Merrick – 4 20. Papers presented by the students Depending on the number of students, students will prepare the presentations of papers alone or in pairs of 2. It is anticipated that the students will present for about 10-12 sessions. Students will present a current literature paper of their choice, but in the field of translation. At the time of the presentation, the students should turn in to Dr. Merrick a three-page paper on what the next series of experiments should be to extend this research. The first page should clearly report the findings of the literature article and the next two pages should describe the student’s proposed experimentation. Subsequently, Dr. Merrick will provide individual feedback to the students. See description of William C. Merrick on the next page: During August 2010, Professor William C. Merrick from the Department of Biochemistry at Case Western Reserve University, Cleveland, Ohio, is visiting The Department of Molecular Biology to give the graduate course "Prokaryotic and eukaryotic protein synthesis". The course deals with the components of translation with special emphasis on their participation in the regulation of protein biosynthesis. A description of the course can be found at http://www.mb.au.dk/da/til/global/stud/phd.htm. Apart from the specific subject of translation, the course offers the opportunity for the student to learn how to read, understand and evaluate original scientific papers. Professor Merrick is renowned as a teacher due to his excellent communication skills, deep engagement and friendly attitude towards the students. The focus of Professor Merrick's research is on the identification of eukaryotic translation initiation factors and the determination of their (regulatory) roles in the initiation pathway.

Knudsen at firstname.lastname@example.org with whom interested students can also sign up for participation in the course.
