Beta-lactams target...
a. Protein synthesis (50S subunit)
b. RNA synthesis
c. Protein synthesis (30S subunit)
d. Cell wall synthesis
I believe the correct answer to be:
Option D) Cell wall synthesis.
As it prevent the synthesis of cell wall so no more bacteria can be formed.
feel free to leave a comment down below for any further query. good rating would be appreciated if you find my answer helpful. thank you.

Synercid binds to sites on the 50S ribosomal subunit. Synercid interferes with Multiple Choice replication. cell wall synthesis. transcription. translation.
Tetracycline is an antibiotic that binds to the 30S subunit of the bacterial ribosome. This information suggests that the most likely mechanism by which tetracycline blocks bacterial growth is to inhibit synthesis of: Question options: A. mRNA. B. rRNA. C. a specific bacterial protein. D. a specific class of bacterial proteins. E. all bacterial proteins.
Tetracycline inhibits protein synthesis by which mechanism? It interacts with the small ribosomal subunit, blocking access of the aminoacyl-tRNA to the mRNA-ribosome complex. It binds to the 305 subunit and distorts its structure, interfering with the initiation of protein synthesis. It binds irreversibly to a site on the 50S subunit of the bacterial ribosome, thus inhibiting translocation. It inactivates the eukaryotic elongation factor, eEF-2, thus preventing translocation.

Which is incorrect about the initiation of translation? Select one: a. 30S subunit binds to mRNA first by recognizing the Shine-Dalgarno sequence on mRNA. b. In bacteria, most of the starting Met codon is specifically for N-formyl methionine (fMet). c. After fMet-loaded tRNA is bound, the 50S subunit binds to make the complete translational complex. d. A complete ribosome complex migrates on an mRNA until it finds the Shine-Dalgarno sequence. e. All of these
a. chromosomes plasmids C. ribosomes d. messenger RNA 14. Protein synthesis in prokaryotes is associated with @Ribosomes b. Centrioles and vacuoles c. Nucleus and cell membrane d. Lysosomes and centrioles 15. Differential stains are a Gram stain and acid fast stain B. Gram stain c. Acid fast stain d. Capsule and flagella stain 16.

Messenger RNA carries amino acids to ribosomes for assembly into proteins. c. In the process of transcription, transfer RNA trans- d. None of the above is true fers its DNA onto a ribosome.
Part A The sigma (?) subunit binds to the core RNA polymerase enzyme. The function of this sigma factor is to recognize and bind to the promoter of a gene so that transcription can be initiated. The closeup shows the secondary structure of the sigma (?) subunit, which consists of four domains. Identify the domains labeled 1-3. The sigma (?) subunit binds to the core RNA polymerase enzyme. The function of this sigma factor is to recognize and bind to...
