Question
Chapter 20, Problem 3TYK
Summary Introduction
To review:
The mechanism of termination of DNA (deoxyribonucleic acid) elongation by dideoxynucleotide triphosphate (ddNTP).
Introduction
The ddNTP are the nucleotides that have a base (adenine, guanine, cytosine, or thymine); three phosphate groups, and a sugar, which lack hydroxyl group at 2’ as well as 3’ carbon. It is different from the usual deoxynucleotide triphosphate (dNTP), which is found in DNA because dNTP have a hydroxyl at 3’ carbon.

The Esp gene encodes a protein that alters the structure of the insulin receptor on osteoblasts and interferes with the binding of insulin to the receptor. A researcher created a group of osteoblasts with an Esp mutation that prevented the production of a functional Esp product (mutant). The researcher then exposed the mutant strain and a normal strain that expresses Esp to glucose and compared the levels of insulin in the blood near the osteoblasts (Figure 2).
Which of the following claims is most consistent with the data shown in Figure 2 ?
A Esp expression is necessary to prevent the overproduction of insulin.
B Esp protein does not regulate blood-s
