Concept Introduction:
These images are provided with the data for the representation of different variable in structure. In PDB file of structure coordinates are used for the representation of protein, RNA and atoms and other different components present in the structure.
(c)
Interpretation:
Double helical region of RNA in structure needs to be determined.
Concept Introduction:
These images are provided with the data for the representation of different variable in the structure. In PDB file of structure coordinates are used for the representation of protein, RNA and atoms and other different components present in the structure.

(d)
Interpretation:
Hit a right click on the image, after that select the ‘Select' option for all proteins. After that, again hit the right click on that image and now select ‘Render' option after this ‘Scheme' and then ‘CPK space fill' option. This results in highlighted ribosomal protein. Now, close the all protein selection tab and now select ‘Nucleic’ then select' ‘CPK space fill' from render

- Exploring the Structure of the 30S Ribosomal Subunit Go to www.pdh.org and bring up PDB file 1GIX, which shows the 30S ribosomal subunit, the three tRNAs, and mRNA. In the box on the right titled ‘Biological Assembly.� click “More Images.� and then scroll down to look at the Interactive Vic By moving your cursor over the image, you can rotate it to view it from any perspective. a. How are the ribosomal proteins represented in the image? b. How is the 16S rRNA portrayed? c. Rotate the image to see how the tRNAs stick out from the structure. Which end of the tRNA is sticking out? d. Where will these ends of the tRNAs lie when the 50S subunit binds to this complex?arrow_forwardMy PDB code: 3GRS residue point: HIS467 mutation: LEU Describe why this position in your protein is important and outline the effects the mutation will have on the 3D structure and the function of your protein.

- The term subunit can be used in a variety of ways. What is the difference between a protein subunit and a ribosomal subunit?arrow_forwardC. The primary structure is the linear sequence of amino acids linked together in a polymer (determined by the genetic code è mRNA codons). Draw the chemical structure of the primary structure of the SerCys-Lys polymer (with the appropriate covalent bonds) that would result if the ribosome completed the condensation reactions. Clearly label the N- and C- terminus of the polypeptide.arrow_forwardSubject: chemistryarrow_forward
- b. What is the difference between the 3' and the 5' ends of a nucleotide chain? C. Do the chains run the same way? d. How are the chains connected? e. Which bases bond to each other? f. What kinds of bonds hold the chain together? 3. What are the main differences between RNA and DNA? 4. Distinguish between the structure of pyrimidines and purines. Explain why adenine bonds only to thymine. 5. Name the five nitrogenous bases in the table below, and put an X in the correct column for each base. Then indicate if the base if found in DNA (D), RNA (R), or both (B) hparrow_forwardDraw onto paper and write your answer below it.
