Erythromycin is best against bacteria because it targets bacterial ribosomal subunits and not eukaryotic ribosomal subunits. What does this mean??

A large ribosomal subunit is on the order of 3200 kDa. The diffusion limit of a nuclear pore is about 40kDa. How do ribosomal subunits ever reach the cytosol?

A large ribosomal subunit is on the order of 3200 kDa. The diffusion limit of a nuclear pore is about 40kDa. How do ribosomal subunits ever reach the cytosol? A.) Ribosomal subunits are endocytosed into the ER. B.) Karyopherin proteins help get them through the pore. C.) They eventually diffuse through the nuclear envelope bilayer. D.) Ribosomes can't get out, because karyopherins to not bind rRNA.

Two ribosomal subunits have sedimentation coefficients of 60S and 40S.

Two ribosomal subunits have sedimentation coefficients of 60S and 40S. Assuming that both subunits have spherical shapes and their densities are equal, calculate the ratio of their molecular weights ( not with the actual molecular weight values).

The ribosomal subunits are not covalently bound and are freely dissociated in the cytoplasm. Explain how the two subunits come together to successfully initiate translation

Ribosmal RNAs (rRNAs) are transcribed from rRNA genes, and eukaryotic ribosome subunits are assembled in the nucleolus.

1) Ribosmal RNAs (rRNAs) are transcribed from rRNA genes, and eukaryotic ribosome subunits are assembled in the nucleolus. How many times must a eukaryotic rRNA molecule cross the nuclear envelope before functioning in translation inside a functional ribosome in the cytosol of the cell?a) neverb) oncec) twiced) three times2) Polymerization of amino acids into a polypeptide requires energy. In terms of chemical thermodynamics, the chemical energy for peptide bond formation in translation technically comes from:a) hydrolysis of GTPb) hydrolysis of ATPc)...

What is translation, where does it occur? How many ribosomal subunits are there, and where are they constructed? What are the P and A sites? What occurs during initiation, elongation, and termination and what are the three steps of elongation. What is the function of the stop codon?

Match the site on the ribosomal subunits (select A, P, or E) to each of the following reaction.

Match the site on the ribosomal subunits (select A, P, or E) to each of the following reaction. The docking site for N-formylmethionine (fMet) tRNA Binding site for the uncharged tRNA before it leaves the ribosome Peptidyl transferase center Decoding center Binding site for IF-3 Binding site for IF-1 Binding sites for incoming charged tRNA Binding site for the deacylated tRNA Binding of the EF-G occurs at this site Binding site for the tRNA attached to the growing peptide...

A reticulate lysate is a system that contains all the components required for translation (ribosomal subunits, tRNA, amino acids, etc) and allows the reaction to be carried out in a test tube. The polypeptide that is synthesized from the system depends on the sequence of the RNA. For example adding the RNA 5’AUGUUUUUUUUUUUU to the lysate directs the synthesis of Met-Phe-Phe-Phe-Phe. 10a. If you add an antibiotic stops translation by specifically blocking the translocation of tRNA from the A site...
