1) You are having a 2.5 mg/ml solution of an amino acid ( mol.wt. = 100). You are need to add the 0.5 µmoles into a test tube. Specify the amount you would pipette? 2) You require a 10mM solution of the potent (and dangerous) transcription inhibitor (mol.wt.500) to do […]

To assess which residues contribute most to the stability of a protein, mutants of the protein are made in which one residue is replaced by amino acid X. The stability of this mutated protein is then measured and compared to the original protein. By repeating the process for many different […]

A recessive allele causes Cystic fibrosis. A man with cystic fibrosis had a son with a normal phenotype. The son marries a woman (unrelated to him) with a normal phenotype. If a normal odds of an heterozygote of getting cystic fibrosis is 1/50, what are the odds that couple’s first […]
