Textbook Question
Chapter 11, Problem 21P
The accompanying chromosome diagram represents a eukaryotic chromosome prepared with Giemsa stain. Indicate the heterochromatic and euchromatic regions of the chromosome, and label the chromosome’s centromeric and telomeric regions.
What term best describes the shape of this chromosome?
Do you expect the centromeric region to contain heterochromatin? Why or why not?
Why are expressed genes not found in the telomeric region of chromosomes?
Are you more likely to find the DNA sequence encoding the digestive enzyme amylase in a heterochromatic, euchromatic, centromeric or telomeric region? Explain your reasoning.

Originally, karyotypic analysis relied only on size and centromere placement to identify chromosomes. Because many chromosomes are similar in size and centromere placement, the identification of individual chromosomes was difficult, and chromosomes were placed into eight groups, identified by the letters A to G. Today, each human chromosome can be readily identified. a. What technical advances led to this improvement in chromosome identification? b. List two ways this improvement can be implemented. c. What clinical information does a karyotype provide?arrow_forwardDefine the following terms: a. chromosome b. chromatinarrow_forward
