Chapter 10, Problem 21CONQ

A typical eukaryotic chromosome found in humans contains about 100 million bp. As noted in Chapter 9, one DNA base pair has a linear length of $\text{0}\text{.34 nm}\text{.}$

A. What is the linear length of the DNA in a typical human chromosome in micrometers?

B. What is the linear length of a $\text{30-nm}$

fiber of a typical human chromosome?

C. Based on your calculation in part B, would a typical human chromosome fit inside the nucleus (with a diameter of $\text{5 µm}$) if the $\text{30-nm}$

fiber was stretched out in a linear manner? If not, explain how a typical human chromosome fits inside the nucleus during interphase.
