In bacteria,the antibiotic tetracycline blocks the site where tRNA molecules enter the ribosome.The most likely reason that bacteria die from treatment with tetracycline is because the antibiotic
A) inhibits the cell from producing the mRNA.
B) causes the tRNA molecules to randomly arrange into proteins that do not function.
C) causes tRNA rather than mRNA to be made into proteins.
D) prevents the bacteria from assembling essential proteins.

Question

Quizplus · Accepted Answer

Tetracycline blocks the site where tRNA molecules enter the ribosome, which prevents the bacteria from assembling essential proteins. Without these essential proteins, the bacteria cannot survive and ultimately die. Tetracycline does not inhibit the production of mRNA or cause random protein arrangement. Similarly, tRNA cannot be directly made into proteins without the involvement of mRNA.
