Question

Choose all of the following designations are accurate for the following fatty acid? a) 20:5^delta 3, 6, 9, 12, 15 b) 20:5^delta 5, 8, 11, 14, 17 c) omega-3 fatty acid d) 19:5^delta 4, 7, 10, 13, 16 e) omega - 6 fatty acid f) polyunsaturated Which of the following base pairs with cytidine? What is/are true of the signal recognition particle (SRP) of the secretory and transmembrane protein synthetic system? a) forms a transmembrane pore in the endoplasmic reticulum membrane allowing the newly synthesized and growing polypeptide to pass through the rough ER membrane into the lumen. b) is a transmembrane protein and therefore is most likely composed of multiple alpha helical regions or beta barrel supersecondary structure. c) is a transmembrane protein of the Golgi apparatus d) releases GDP and binds GTP to perform its function. e) is a receptor on the rough endoplasmic reticulum which recognizes and binds the SRP-ribosome-signal peptide complex, Choose all of the statements that apply to the following figure. a) contains a purine b) contains a pyrimidine c) nucleoside d) nucleotide e) ribo f) deoxyribo

Explanation / Answer

14. C, D, E & F are Correct. C is correct because, the C3 position from the end of fatty acid chain possess C=C; D is correct because The fatty acid structure contain, 19 carbons and C=C double bonds present in between 4&5, 7&8, 10&11, 13&14, 16&17.; E correct because the C6 position from the end of fatty acid chain possess C=C; F is correct because The fatty acid chain contain several double bonds.

15. Cytidine is a Nucleoside (Contain Sugar and Cytosine) that base pairs with Guanine (2 Amino, 6 Oxo Purine). So Answer is B

16. Answer is E.

17. a is correct. It is Purine that is Adenine (6-Amino Purine); d is correct. Because it is Nucleo tide that contain Nitrogen base (Adenine), Pentose Sugar (Ribose) and Phosphoric acid. e also correct. The pentose sugar is Ribose (The sugar possess 2' OH group).

Over all the structure is Cyclic AMP which is popular secondary messenger in signal transduction pathway
