The cell holds an organism’s genetic information in the sequence of nucleotides, or nitrogen bases, found in
that organisms DNA. When it is time for cells to reproduce that DNA becomes tightly coiled into the
structure shown below.
1. Identify, draw, and label the structure in the box.
2. Where would you find this structure in the cell?

All non-sex cells in an organism are said to be diploid. This means that they have a full set of chromosomes.
3. After going through the cell cycle, how many chromosomes would be in one daughter cell of a potato?
4. What is the haploid number for a goldfish?
5. Does the number of chromosomes reflect the complexity of an organism?

Karyotypes are one of many ways scientists and doctors analyze an organism’s chromosomes, genes, and
traits. Karyotypes can identify gender and possible diseases and disorders.
22.
23.
Identify Karyotype A as normal or abnormal.
Identify Karyotype B as male or female.

Scientists have completely mapped the human genome. Chromosome painting, karyotyping, and DNA
fingerprinting are just a few of the tools used to analyze DNA, chromosomes, and the entire genome.
