Chapter 13 Question 1 Pleiotropy is when A. one gene controls the expression of another gene B. when one gene has many e8ects on the organism C. when one character of an organism is influenced by several genes D. two genes are the same Question 2 Polygenetic inheritance is when A. two genes are the same B. when one character of an organism is influenced by several genes C. when one gene has many e8ects on the organism D. one gene controls the expression of another gene Question 3 Epistasis is when A. when one gene has many e8ects on the organism B. two genes are the same C. when one character of an organism is influenced by several genes D. one gene controls the expression of another gene Question 4 Which nucleic acid base is not in DNA? cytosine guanine thymine uracil Adenine Question 5 What is the purpose of topoisomerase during DNA replication? A. Adds nucleotides to the growing strand DNA B. Stabilizes single-stranded DNA until it can be used as a template C. Enzymes that untwist the double helix at the replication forks D. Corrects over winding of the uncoiling DNA strand Question 6 What is the purpose of helicase? A. Stabilizes single-stranded DNA until it can be used as a template B. Corrects over winding of the uncoiling DNA strand C. Enzymes that untwist the double helix at the replication forks D. Adds nucleotides to the growing strand DNA Question 7 What is an Okazaki fragment? A. A fragment of RNA that adds nucleotides to the leading strand of the DNA template B. A fragment of newly replicated DNA on the lagging strand of the DNA template C. A fragment of newly replicated DNA on the leading strand of the DNA template D. A fragment of RNA that adds nucleotides to the lagging strand of the DNA template Question 8 What is the complementary DNA strand for a gene with a code of TAG GGT ACC ACT A. AUC CCT TGG AAT B.
