The American Society of Anesthesiologists (ASA) has established the criteria for classifying the patient’s

Ribosomes and ribosomal RNAs are usually characterized by their sedimentation coefficients (S values). Which of the following have sedimentation coefficients of 50S?

Which of the following mRNA segments contains both a translation start codon and a translation stop codon?

The small and large subunits of ribosomes contain ribosomal RNA and numerous proteins. The large subunits of prokaryotic ribosomes have which composition?  

Eukaryotic rRNAs are initially synthesized as 45S transcripts that are converted into 28S, 18S, and 5.8S rRNAs. SnoRNPs (small nucleolar ribonucleoproteins) are involved in processing the rRNAs in which way?

Coenzyme Q functions by carrying electrons and protons between protein complexes of the electron transport chain.  The protein complex that does not interact with coenzyme Q is:  

Guanylyl transferase is an enzyme in eukaryotic cells involved in:

In the initiation of protein synthesis in E. coli, which protein factor binds to the initiator aminoacyl-tRNA (f-Met-tRNA) in the formation of the 30S initiation complex?

Base excision repair is a DNA repair mechanism that acts on single bases damaged by chemical modification.  The repair pathway consists of several enzymes: (1) DNA polymerase I, (2) DNA ligase, (3) DNA glycosylase, (4) apurinic/apyrimidinic endonuclease, and (5) excision exonuclease.  The correct order in which these enzymes act is:

The acceptor stem of a tRNA molecule, with a conserved CCA sequence, is the site of binding of amino acids to the tRNA. The acceptor stem is located in which region of a tRNA molecule?
