Question

Hello I really need help with these BIO-1 questions. Could you guys please answer all of the multiple choice questions. I know it seems like a lot but i would highly appreciate it becuase i really need help on them. Thank you guys! I truly appreciate it.

27. The homologous chromosomes are separated from each other during A. Meiosis B. Meiosis II C. Both Meiosis I and meiosis D. None of the above 28. During DNA replication, the Okazaki fragments represent the newly synthesized DNA along the: A. leading strand and are joined together by helicase .lagging strand and are joined together by helicase C. leading strand and are joined together by ligase D. lagging strand and are joined together by ligase E. none of the above 29. During Glycolysis of glucose, the ATP molecules are synthesized by: A. oxidative phosphorylation B. substrate level phosphorylation C. both substrate level phosphorylation as well as oxidative phosphorylation D. none of the above is correct 30. The mitotic spindle that is involved in the separation of duplicated sister chromatids during mitosis is made up of microtubules. A. True B. False 31. Which process utilizes base-pairing rules between nucleotides as a part of the mechanism? A. DNA replication, both parental strands used as template B. Transcription of RNA, one strand of DNA used as template C. Translation, anti-codon of tRNA recognizes codon of mRNA D. All of the above E. None of the above 32. A reaction has a G of-5.6 kcal/mol. Which of the following would most likely be true? A. The reaction could be coupled to power an endergonic reaction with a G of +8.8 kcal/mol B. The reaction is nonspontaneous. C. To take place, the reaction would need to couple to ATP hydrolysis. D. The reaction would proceed by itself but might be very slow E. The reaction would result in products with a greater free-energy content than in the initial reactants.

Explanation / Answer

27. They separate in meosis II. Option B is correct.

28. In the laggind strand synthesis the okazaki fragments form and connected through DNA ligase. Option D is correct.

29. The both types of phosphorylaton take place during glycolysis. Therefore, option C is correct.

30. They made of microtubules (option A- True).

31. The base pairing rule that is A to T and G to C attachments follows in DNA replication. The option A is correct.

32. According the rule of energy deployment in chemical reaction, if a reaction takes energy to complete, then it will require continuous energy from other source to continue its reaction. On the other hand, the exergonic reaction where energy expels out, there is no need of extra energy from outer source to make the reaction continuous. Therefore, the option D is correct. However, the process may take more time to complete.
