WGU Biochemistry Module 1 Quizzes and Terms with COMPLETE SOLUTION 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. Thymine, Uracil, Adenine, Cytosine b. Adenine, Thymine, Cytosine, Uracil c. Adenine Guanine, Uracil and Thymine d. Adenine, Guanine, Thymine, Cytosine - ✔✔d. Adenine, Guanine, Thymine, Cytosine 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. 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'-TACTAGGAA-3' b. 5'-ATGATCCTT-3' c. 5'-UACUAGGAA-3' d. 5'-GCAGCTTCC-3' - ✔✔a. 5'-TACTAGGAA-3' The bases on the newly made daughter strand are complementary to the bases on the template strand, but with the opposite 5' and 3' orientation. Which of the following statements is TRUE about RNA? Select one: a. All of these b. RNA nucleotides include the bases A, U, C, and G. c. There are several types of RNA in the cell, including mRNA, rRNA, and tRNA. d. RNA is single stranded and contains a ribose sugar in the sugar-phosphate backbone. - ✔✔a. All of these All of these statements about RNA are true. The cell contains mRNA, rRNA, and tRNA molecules, RNA is single stranded, RNA contains a ribose sugar in the sugar-phosphate backbone, and RNA nucleotides include the bases A, U, C, and G. What is the complementary DNA strand for the DNA sequence 5'-ATT CGG GCT CCC -3'? Select one: a. 5'- GGG AGC CCG AAT -3 b. 5'- UAA GCC CGA GGG -3' c. 5'- ATT CGG GCT CCC -3' d. 5' - CCC TCG GGC TTA -3 - ✔✔a. 5'- GGG AGC CCG AAT -3 The correct answer is 5'- GGG AGC CCG AAT -3', when written in the conventional way starting with the 5' end of the strand. A research scientist is trying to create a new strain of bacteria that can produce a protein needed for her research. Which of the following molecules will act as a template in creating the protein? Select one: a. Ribozyme b. transfer RNA (tRNA) c. messenger RNA (mRNA) d. Ribosomal RNA(rRNA) - ✔✔c. messenger RNA (mRNA) [Show More]
