13.3: A Chromosome Consists of a DNA Molecule Packed with Proteins
You Must Know:
- The general differences between bacterial chromosomes and eukaryotic chromosomes
Key Terms: Nucleoid, Chromatin, Heterochromatin, Euchromatin
IN CLASS READING of Concept 13.3: Pages 267-269
1. Define the Key Terms above.
FROM PAGE 267
2. Decribe the main component of the genome in most bacteria.
3. Determine whether the nucleoid in bacteria is surrounded by a membrane or not.
4. Calculate the total length of DNA in one human somatic cell in centimeters and then convert to feet.
5. List the 2 main biomolecules found in a eukaryotic chromosome.
FROM PAGE 268-269
6. Explain what happens to DNA's ability to be transcribed as it becomes more highly packaged.
7. Create a t-chart comparing heterochromatin with euchromatin, being sure to include which form can be transcribed and which one cannot.
