A single polypeptide chain houses the transferase and debranching enzyme. Cite a potential advantage of this arrangement.
For each term, indicate 1) what kind of molecule the term refers to (DNA, RNA, protein) and 2) what process it most directly functions in. NOTE: also know whether or not it
functions in prokaryotes, eukaryotes or both!! (it was just too unwieldy to add all those option to this question)

The answer given in problem 31. 17 is inadequate for me, and I simply don't understand the explanation for the answer...
The problem is: Ribosoms were isolated from bacteria grown in a "heavy" medium (13C and 15N) and from bacteria grown in "light" medium (12C and 14N). These 70S ribosoms were added to an in vitro system engaged in protein synthesis. An aliquot removal serveral hours later was analyzed by density-gradient centrifugation. How many bands of 70S ribosoms would you expect to see in the density gradient?
Is it possible to give a more comprehensive explanation? :)

- The mechanical changes that ribosomes undergo to be able to translate are driven by energy from: 1. ADP hydrolysis 2. GTP hydrolysis 3. Concentration gradient 4. ATP hydrolysisarrow_forward. In the early days of ribosome research, before the exact role of ribo- somes was clear, a researcher made the following observation. She could find, in sedimentation experiments on bacterial lysates, not only 30S, 50S, and 70S particles but also some particles that sedi- mented at about 100S and 130S. When she treated such a mixture with EDTA, everything dissociated to 30S and 50S particles. Upon adding divalent ions, she could regain 70S particles, but never 100S or 130S particles. (a) Suggest what the 100S and 130S particles might represent, in light of current knowledge of protein synthesis. What important dis- covery did the researcher miss? (b) Why do you think reassociation to 100S and 130S particles did not work?arrow_forwardChoose the option that is best described by each of the following statements 1 1. Attacks the N-terminus 2.
