Own studies

Time is reserved for individual studies of the textbook, for preparing for experimental work

and for preparing for the lab report and the presentation of the experimental work.

Group discussions

All students should read the following chapters in the textbook. The chapters will be

discussed during the four group discussions as indicated. During each group discussion, a

teacher will be present.

Experimental work

The students will be divided into three groups. Each group will participate in one of the three

wet-labs as detailed below. Each experiment will have its own time requirements and each

group will follow that particular time requirement. This means that each group will have a

somewhat different schedule that is dictated by the experimental work. At all times when the

experimental work allows, the students have time for their own studies (reading the text book,

preparation of lab. report and presentation of the experimental work). Each group will present

their work for the other students (10 May).

Lab. report

Students must hand in a written report of their experimental work. The report should be

written in English. It should present the purpose of the experimental work, the principal

behind the methods used, the results, and a discussion in which the results are evaluated from

a methodological point of view.

The three experiments are:

1. Analysis of gene expression in Saccharomyces cerevisiae

Methods: Transformation of yeast cells, galactose induction, extraction of proteins and

Western blot analysis, extraction of RNA and Northern blot analysis, fluorescence

microscopy.

2. Analysis of stress responses by qPCR in barley plants

Methods: primer design, gDNA isolation, genotyping mutants, RNA isolation, cDNA

synthesis, RT-PCR, navigating TAIR web site (www.arabidopsis.org)

3. RNA interference – knockdown of nuclear Williams syndrome transcription factor

(WSTF)

Methods: Growing human/murine cells, transfection of mouse cells, light- and

fluorescence microscopy, Western blot analysis.

Study visits

There will be two study visits during the course at the times and places indicated in the

schedule. It is important that all students show up at the correct time.

1. SciLifelabs. Title: Next generation DNA sequencing. Joakim Lundeberg and Patrik

Ståhl.

2. Thomas Burglin lab: C. elegans as a model system.

Case Study

A Case Study will take place on Thursday 18 April (9.30-12.00), with follow-up discussions

planned for Thursday 23 May (9.30-12.00). Students will be given a question on Thursday 18

April, to work on by themselves before the final written examination (Monday 10 June 9.00-

12.00). Students have up until and including Monday 10 June to hand-in their answer sheet to

Jamie Morrison. A student failing to hand in their answer sheet before the deadline will forfeit

the 2hp allocated for this part of the course.

Methods and Concepts in Life Sciences VT-13

Experimental Work

The course contains three separate experiments. The students will be divided into three

groups. Each group will perform only one of the experiments, but should be familiar with the

principles exemplified in all four experiments. Each experiment has a contact person who will

be in charge of the experimental work.

Each experiment will follow its own pace. This means that each group of students will have a

different schedule for the experimental work. These scheduled will be evident from the

planning of each experiment. When there is no experimental work, time can be used for

individual studies.

Each student has to write a laboratory report that will be checked and accepted by the contact

person responsible for each experiment. Every group also has to give a presentation (short

written summary handed out before the presentation and a short seminar) of their

experimental work for the other students (Thursday 10 May). The accepted written report and

the presentation are both compulsory parts of the course (see grading criteria).

Schedule for presentations of experimental work, Thursday 16/5 2013 at 9.30 (FB105)

Each group gives one presentation. The presentation can be given by one person in the group,

or together by several persons.

Each presentation shall describe the background for the experimental work, the individual

experiments, the results obtained by the group and a discussion of the results from a

methodological point of view. Emphasis should be on extracting the information that each

experiment gave and a discussion of theoretical and practical limitations.

Each group is given 30 minutes, including discussion and questions involving the whole

course.

Grading criteria, Methods and Concepts in Molecular Life Sciences

The grading is based on:

1. The result from the written examination.

2. The result from the case study.

3. That you pass the experimental work, including presentation.

This means that in order to pass the course, you have to fulfill the criteria for pass for the

experimental work (see below) and you have to have at least 60% of the maximum points in

the written examination.

It is highly recommended that you attend the lectures, group discussions and site visits since

these are important parts of the course and since questions in the written examination will

partly cover these parts of the course.

Grading criteria for the written examination and case study (seven-point grading scale)

The grade A is awarded if the student has achieved at least 95% of the maximum points

available in the written examination.

The grade B is awarded if the student has achieved at least 85% of the maximum points

available in the written examination.

The grade C is awarded if the student has achieved at least 75% of the maximum points

available in the written examination.

The grade D is awarded if the student has achieved at least 65% of the maximum points

available in the written examination.

The grade E is awarded if the student has achieved at least 60% of the maximum points

available in the written examination.

The grade Fx is awarded if the student has achieved at least 50% of the maximum points

available in the written examination.

The grade F is awarded if the student has achieved less than 50% of the maximum points

available in the written examination.

Grading criteria for the experimental work (two-point grading scale): Pass or Not Pass

In order to pass the experimental work that are part of the course, you must in a group of 4-8

carry out and subsequently individually present the experimental work. The presentation is to

be in the form of a short seminar and in the form of a written report. The report shall be in

English and is to have the following structure, unless otherwise specified.

Title

Introduction

Describe briefly and clearly the aim of the exercise and describe the theoretical background.

Materials and Methods

Summarize what you have done (without simply reproducing large parts of the lab

instructions). Specify clearly any deviations from the lab instructions. Feel free to supplement

the text with figures and flow diagrams.

Results

Raw data is to be presented in tables such that it is easy to gain an overview. Each table is to

have a title and it is to be clear what the rows and columns of the table represent. Large

quantities of raw data may be presented as an appendix. Calculations are to be presented such

that each step is clear and such that the calculation is easy to follow for the person assessing

the report. The results of the calculations are to be clearly presented. Any graphs included

must be attractively drawn and the axes labeled with the correct units.

Discussion

Summarize and interpret the results that have been presented in the preceding section.

Conclusions must be clearly expressed and well supported. Answer any questions that the lab

instructions pose. If the results deviate from the expected, the reasons for this must be

discussed and possible sources of error must be described.

References

References are to be given if they lie outside of the lab instructions or the compulsory course

literature.

General Information

It is preferred that the report is written on computer. If this is not the case, it must be written

with tidy and easy-to-read handwriting. Write the report as running text with complete

sentences and make every effort to use a clear, correct and objective language. Avoid using

informal language and laboratory jargon. Check the spelling carefully! Follow the rules laid

down for nomenclature (the scientific names of organisms) and other scientific terminology

(such as the names of genes and proteins).
