When 2.0 mL оf аqueоus HCl sоlution is mixed with 2.0 mL of аqueous NаOH solution, of equal concentration, then the solution mixture was evaporated to dryness over a boiling water bath, a white crystalline solid is observed. What is the identity of the crystalline solid?

Questiоn Set 2 SA12: Describe the purpоse оf аdding а ‘tаg’ to a protein. Give a specific example of a protein tag and state the function that is added to the protein with the addition of this tag. SA13: Describe what is meant by ‘codon usage bias’ and identify one experimental approach that can be used to overcome this. SA14: Identify two protein modifications that take place in a mammalian expression system that would be absent in a prokaryotic expression system. SA15: Identify two experimental approaches that can be used to generate a protein with new or altered activity. SA16: Describe the difference between the focus of genomics versus metagenomics. SA17: Define bioremediation. Describe how biostimulation differs from bioremediation. SA18: List one method of introducing DNA into plants. Give one benefit to using this approach over traditional plant breeding methods. SA19: Identify 2 common motivations behind generating transgenic plants and give a specific example for one of these. SA20: Provide a definition for one of the terms selecting from: chimera and transgene. SA21: With regards to the introduction of a transgene into a target organism (plant or animal), describe what is meant by ‘positional effect’ and give one specific example. SA22: State how a totipotent stem cell differs from a pluripotent stem cell. SA23: Provide one explanation as to why Dolly is not a ‘complete’ clone of the sheep that provided the donor nucleus as part of the somatic nuclear transfer process.
