How do you think the existence of multidomain proteins relates to complexity in higher eukaryotes?

The attached paper is for your reading, if interested. It discussed about structure-based inhibitor.

How can you define domain and motif? Is there any significance in bioinformatics or in proteomics?

 List the important features of the primer that you have checked for to ensure the success of your experiment (2 marks).

Biology assignment primer design

If your role were to generate an inactive mutant of the protein encoded by the gene sequence below in an E. coli expression system, show the primers you would design to generate that mutant. Base your design on the mutations tested in adenylate kinase reported in Saraste et. al, (1990) (4 marks).

List the important features of the primer that you have checked for to ensure the success of your experiment (2 marks).

Once you have designed your primers, draw out a flow diagram, with a few explanatory notes, showing the experimental steps needed to perform this mutagenesis experiment (refer to the lecture notes for help) (2marks).

One Chinese researcher has modified human embryos so that they are not susceptible to HIV. His work was condemned by the international scientific society:Discuss?

Gene editing methods have been around for years but involved cumbersome mechanisms. In 2015 the CRISPR gene editing system has made this method easy to do. One Chinese researcher has modified human embryos so that they are not susceptible to HIV. His work was condemned by the international scientific society:Discuss

A recent clinical study demonstrated a possible connection between coffee consumption and heart health. The researchers performed a 6-week trial with 191 individuals, all of whom were heavy coffee drinkers (average of 5 cups/day) before the experiment, but none of whom were smokers. They divided the 191 participants into three groups: no coffee consumption, 1-3 cups/day, and four or more cups/day. They measured blood levels of cholesterol and homocysteine as indicators of heart health. Only the no-coffee group showed a significant drop in both indicators. Previous studies had demonstrated that decreases of the magnitude observed in the no-coffee group could cut the incidence of heart disease by 10-15%.

What is the purpose of the Tris-Acetate-EDTA (TAE) buffer that the agarose gel is prepared with and submerged in for running? What would happen if you used water to prepare and run the gel instead of TAE buffer?
