Study Notes
DNA Structure and Packaging
- DNA has secondary structures; the question asks how many (1, 2, 3, 4, or 5).
- Secondary structures have names (needs to be answered).
- A specific secondary structure predominates.
- DNA has tertiary structures; the question asks how many (2, 3, 4, 5, or 6).
- Tertiary structures have names (needs to be answered).
Histone Proteins
- There are a specific number of histone protein types (2, 3, 4, 5, or 6).
- Histone proteins have names (needs to be answered).
- Multiple histones aggregate in the nucleosome core.
- Histone proteins play a significant role in DNA packaging (needs to be clarified).
- Histone proteins are critical for DNA organization.
DNA Packaging States
- There are a specific number of DNA packaging states (3, 4, 5, 6, 7, or 8).
- Each state has a name (needs to be answered).
- Transitions between heterochromatin and euchromatin occur, and states are altered.
- Open chromatin (euchromatin) facilitates gene expression.
