Question 18 (3 points) Saved What characteristics make the gene for small-subunit ribosomal RNA particularly well suited for studies of the phylogeny of all living things? Choose all options that are correct. More than one option is correct It is present in all extant living organisms It has always been under very strong stabilizing selection, such that very few differences accumulate per year It was present in the first living thing The gene performs the same function in all living...

The 16S rRNA is not an mRNA but rather is a catalytic RNA that is a functional component of prokaryotic ribosomes. Would the genome annotation approach you used during the genome annotation lab have worked to identify a 16S ribosomal RNA gene? Why or why not?

In the PCR exercise you described why we amplify the 16s ribosomal RNA gene. What other genes might help us to identify specific bacteria? In other words, what traits could be sequenced that are unique to bacteria?

The mRNA, small ribosomal subunit, and large ribosomal subunit form a tightly assembled complex prior to the binding of the initiator tRNA True False As important as the rRNA components are to the structure of the ribosome, it is the ribosomal proteins which actually catalyze the formation of peptide bonds. True False

In Bacteria, translation of nascent RNA transcripts is often initiated before transcription is terminated. When this occurs: Select one: a. RNA is transcribed 3'=>5' and amino acids are added to the carboxy terminus of the growing polypeptide as the ribosome moves 5' => 3' along the mRNA b. RNA is transcribed 5'->3' and amino acids are added to the amino terminus of the growing polypeptide as the ribosome moves 3'=> 5' along the mRNA c. RNA is transcribed 3'=> 5'...

1.What sequence upstream of AUG in prokaryotic mRNA facilitates recruitment of the 30S ribosomal subunit by base pairing with 16S ribosomal RNA? A. The Pribnow box B. The Shine Dalgarno sequence C. The TATA box D. The -35 region E. A stop codon 2.What is the role of the Shine-Delgarno sequence in prokaryotic mRNAs? It specifies the site of translation initiation - ? It specifies the site of polyA addition RNA splicing RNA export It specifies the site of translation...

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.
