Question

A cell is lacking in its supply of amino acids. Which of the following will occur?
A.
mRNA will not be formed because enzymes may not be present.

B.
The ribosomes will not work properly because there will be no proteins.

C.
tRNA may not be able to fulfill its job.

D.
all of the above

Answer 1

If this is a question for your Exam, I would say this is one tough and tricky one. Answer D is definitely not wrong but I am just about certain to say that I would choose C.

The question states a lack of amino acids supply. Formation of mRNA requires RNA polymerase which is an enzyme and it is made up of amino acids. However, the keyword becomes "supply". The question never mentioned anything about the proteins that should already be in the cell. For example if the question is changed to, "A cell lacking in protein, which of the following will occur". Then I will take A as a possible answer because there is a lack of protein.

Answer B is kind of the same as my reasoning for answer A.

Remember that during cell division, in the G1 and G2 phases, the cells grow and make important molecules such as organelles and enzymes. The cell is not able to degrade your protein within. (Quite certain about that) If your cells do not have enzymes and ribosomes to begin with, the cell most probably would not even be formed. Remember that from G1 to S phase, there is a biomolecular signal that is required for the cells to enter the S phase. The signal is determined by the "growth" of the cell. When the cell growth is done to a certain extent, it would get the signal and then it continues.

So, with this explanation, I would choose my answer as C. When the cell is lack of amino acids, it should not affect the organelles and enzymes within because they were already formed and cannot be disintegrated or broken down under the above circumstance.

Answer 2

Background info you need: where do amino acids fit in with a cell? what do amino acids 'do'? This question can be answered by thinking about the macromolecule that amino acids make up: proteins.

Now you need to consider how proteins are made in a cell....DNA ->mRNA->protein...and all the ccell structures and molecules that are needed.

Hope this helps!

Answer 3

D Because it would depend on the amino acids omitted. The omission of certain amino acids could cause one or all of these things to happen. It could also (rarely) cause no problems.

Answer 4

1. It enters the cytoplasm and moves toward ribosomes. 2. mRNA Only 3. All of the Above

Answer 5

d. all of the above because proteins make up enzymes and they are made out of aa
the ribosomes make the proteins and enzymes
and tRNA colects the aa

Answer 6

It's D Stupid.

Answer 7

In the time it took to write this question the correct answer could be found in the biology book thats never been open in your locker.

Answer 8

Its D
