An Important Laboratory Skill for Molecular Biology
In the lab, work with DNA and enzymes frequently involves measuring very small volumes, often in the
microliter range. A microliter (l) is one millionth of a liter. To make these

1. a. If n = 10 in a diploid organism, how many DNA molecules are found in metaphase I? _40_
1. b. How many telomeres? _80_
If n = 10, then 2n = 20. Metaphase I occurs after replication (S phase), so th
