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
My choice is D. Please check!
Yes.
Or it could be C.
Yeah, I am confused as to whether it is D or C... Thank you for the help though :)
the answer is D
To determine the correct answer, let's analyze each option:
A- mRNA will not be formed because enzymes may not be present.
In this scenario, if a cell is lacking in its supply of amino acids, it means that there won't be enough building blocks to create proteins. However, the formation of mRNA is not directly dependent on the availability of amino acids. mRNA synthesis is carried out by another class of enzymes called RNA polymerases, which do not require amino acids for their activity. Therefore, option A is incorrect.
B- The ribosomes will not work properly because there will be no proteins.
This option suggests that the ribosomes, responsible for protein synthesis, will not work properly due to the absence of proteins. Since ribosomes are composed of both proteins and RNA molecules, a deficiency in amino acids could indeed impair ribosomal function. Consequently, option B is a possible consequence of a lack of amino acids.
C- tRNA may not be able to fulfill its job.
tRNA (transfer RNA) molecules are involved in delivering amino acids to the ribosomes during protein synthesis. They are responsible for attaching the appropriate amino acid to the growing peptide chain on the ribosome. Without sufficient amino acids, tRNA molecules may not be able to fulfill their role and protein synthesis may be compromised. Therefore, option C is a conceivable outcome of an amino acid deficiency.
Based on the analysis above, it is evident that both options B and C are feasible consequences of a cell lacking in its supply of amino acids. Therefore, the correct answer is indeed D - all of the above.
