Answer:
I believe that the best answer to the question: How is it that the same tertiary structure of a protein can result from different primary structures? Would be, B: None of the above.
Explanation:
This is probably the best choice from all the ones in the list simply because due to specific portions of the other answers they make the statement incorrect.
It will help to remember this: proteins have primary, secondary and tertiary structures because when they first emerge from the trascription process from mRNA, they are a simple string where the most important factor is the sequence of aminoacids. It is this sequence which will determine the folding factor. However, there is another factor that must always be kept in mind; environmental factors (temperature, medium where the protein is, as well as location where it is being produced) will also play a role on how the folding will happen and on which of the aminoacids.
The evolvement of a protein chain from its primary, to its secondary and then tertiary shape (the only functional, or known as native state) depends on which of the aminoacids in a specific sequence has the necessary elements to form bonds (hydrogen bonds) with others and thus start the folding process.
Could be a graduated cylinder. Hope this helps :)
Answer:
This question lacks options, the complete question is: What do you think would have the greatest effect on the body—a harmful mutation in a pluripotent embryonic stem cell, or a harmful mutation in an adult multipotent stem cell?The correct answer is a harmful mutation in a pluripotent embryonic stem cell.
Explanation:
Pluripotent Stem Cells can self-renew and differentiate into any of the three germ layers, which are: the ectoderm, the endoderm and the mesoderm. These three germ layers subsequently differentiate to form all the tissues and organs within a human being. If during embryonic development, genetic mutations - alterations in genes - occur in the embryonic stem cell, they pass to daughter cells as a consequence of cell division, and an individual is generated whose cells differ at the genetic level. Multipotent stem cells are organospecific cells, that is, they can give rise to any type of cells but from a specific organ (a lung, a kidney or the brain). Their differentiation ends the moment they specialize and become a cell with a specific function within a specific tissue or organ. If there were a mutation in these cells, it would damage a specific designed tissue or organ.
<span>I believe is answer is the temperature is too low. If the main fermentation products will be always ethanol in the yeasts chosen for alcoholic fermentation, since the yeasts are growing well on the maltose, the temperature may be too low which causes poor extraction of color and tannins in red wines and can also cause sluggish fermentations and production of high levels of ethyl acetate.</span>
