14. DNA Synthesis

The scientist/s that was/were given credit for first determining the structure of DNA is/are:

The scientist/s that used x-ray diffraction to help reveal the structure of DNA is/are:

In the polymerization of DNA, a phosphodiester bond is formed between a phosphate group of the nucleotide being added and which of the following atoms or molecules of the last nucleotide in the DNA strand?

Within a double-stranded DNA molecule, adenine (A) forms hydrogen bonds with thymine (T), and cytosine (C) forms hydrogen bonds with guanine (G). What is the significance of the structural arrangement?

In a nucleosome, the DNA is wrapped around a. histones. b. ribosomes. c. polymerase molecules. d. a thymine dimer.

MAKE CONNECTIONS Although the proteins that cause the E. coli chromosome to coil are not histones, what property would you expect them to share with histones, given their ability to bind to DNA (see Figure 5.14)?
