C785 Biochemistry Module 1 Quiz 2020 – Western Governors University

C785 Biochemistry Module 1 Quiz 2020 – Western Governors University You are designing a piece of DNA for a project and must select the appropriate nitrogenous bases. Which combination of nitrogenous bases would you find most suitable for your work? Select one: a. Adenine, Guanine, Thymine, Cytosine Correct! These nitrogenous bases, in combination with deoxyribose sugar and phosphate, form the nucleotides that are bonded together to form a long polymer of DNA - the carrier of genetic information. b. Adenine Guanine, Uracil and Thymine c. Thymine, Uracil, Adenine, Cytosine d. Adenine, Thymine, Cytosine, Uracil The DNA sequence 3’-ATGATCCTT-5’ is part of the template strand during DNA replication. Which of the following would be the correct sequence for the newly made DNA? Select one: a. 5’-ATGATCCTT-3’ b. 5’-GCAGCTTCC-3’ c. 5’-TACTAGGAA-3’ d. 5’-UACUAGGAA-3’ Incorrect. In this option U has been used instead of T. Although this is how an mRNA molecule would be created from the DNA, it is not the appropriate complementary base when replicating the DNA. Recall that during replication, the bases on the newly made daughter strand are complementary to the bases on the template strand using the following base pairing rules: A with T and G with C.
