6.1-1 DNA and Inheritance Use the information from Section 6.1 of your Student Book to fill in the blanks. 1. All new cells arise from the division of and the information needed to make each cell is contained in the cell's 2. In eukaryotes, DNA is stored in a membrane-enclosed The DNA is organized into one or more pieces called that appear as X-shaped objects during mitosis or meiosis. 3. In prokaryotes, the DNA is usually present in the shape of a single There may be additional smaller pieces of DNA, called 4. In the 1800s, did breeding experiments with pea plants and showed that traits are passed from parent to offspring in predictable ways. He proposed that different traits are passed on by different factors; we now call these factors 5. Genes carry instructions for building 6. In eukaryotes, the DNA is condensed by wrapping around proteins called 7. Humans have pairs of chromosomes. Each set of human chromosomes contains more than 20 000 8. Most eukaryotes are which means that they have two sets of chromosomes per cell. Many plants may contain 1, 3, 4, or 6 sets of chromosomes per cell; these are called or respectively.

6.2-1 How Much DNA? Use the information below to help you solve the problems. • Each copy of the genome contains 3 billion base pairs (3 x 10"). • Each human cell contains two copies of the genome. • The number of cells in a human body is estimated to be about 50 trillion (5 x 10). One complete turn of DNA = 10 base pairs = 3.4 nm 1. How long is the DNA in one cell? Number of base pairs %3D Length per base pair = nm Length per cell = (Number of base pairs) x (Length per base pair) %3D nm (Convert to meters: 1 000 000000 nm = 1 m) 2. What is the total length of DNA in a human being? Length of DNA per cell (from Problem 1) = Total length = (Length per cell) x (Number of cells) = m (Convert to kilometers: 1000 m = 1 km) km 3. Compare this to the distance from Earth to the Sun: 150 000 000 km. Do you have enough DNA to reach to the Sun? 4. Yeast has about 12 000 000 base pairs. What is the length of its DNA? 5. Compare the length of yeast DNA to the length of human DNA. Explain the significance of this difference.
