Hypothesis: since the normal substrate for the enzymes is lactose, adding lactose along with ONPG will reduce the rate of yellow color formation.
Remember the independent variable on the activity of the enzyme beta-gal not E.coli
1. List your control and the independent and dependent variable and explain why yhese are your control, independent, and dependent variables.
2. Describe your experimental design: it is enzymes break down some times lactose and sometimes OMP. add lactose along with ONPG then reaction will be reduced since ONPG and lactose are a substrate.
3. does this experiment support or refute your hypothesis? why and why not? you may neeed to do some research to help explain your results and any ideas that are not yours should be cited.
explain How will the net charge of a typical protein change.The table below indicates approximate values for these at 25C. For reference, the delta H(ionization) for Tris is 47kJ/mole.
Consider the HIV enzyme called protease. The amino acid residues at the active site are highly hydrophobic. In designing a drug that would bind to the active site and jam it, researchers should use which sort of molecule.
explain short-chain or long chain fatty acids. When bacteria growing at 20 degree celsius are warmed to 30 degree celsius, are they more likely to synthesize membrane lipids with.
Two consecutive crosses, with the first between pure-breeding parents that differ in two phenotypes to create an F1 generation, and the second in two F1 progeny to create an F2 generation.
Multicellular animals have some mechanism to control cell mass that we do not understand; for in case, salamanders of different ploidies are the same size such that a haploid, a diploid, and a pentaploid organism are about the same size.
What would be TRC for a male with the genotype AABbCcDD? For a female. In contrast, each dominant allele in an individual's genotype contributes 12 ridges to the TRC in males and 10 ridges to the TRC in females.
which nucleotide sequences represents complement to DNA
Both endocrine and nervous system are major regulating systems of the body; however, the nervous system has been compared to any post mail delivery system and the endocrine system to the pony express. In brief explain this comparison.
The following cross involving three genes was performed: Aa Bb Cc x aa bb cc, and the phenotypes and number of progeny are shown below. Each pair of alleles exhibits simple dominance and recessiveness.
Face and body creams that are marketed to women in order to "rejuvenate the skin, and get rid of the fine lines and wrinkles" consists of large quantities of collagens.
How various different types of gametic combinations.
A molecular level description means that you must explain the structure of water and how that structure leads to the observation made- in this case that water beads on waxes.
