Which one of the following histone proteins is attached to the linker DNA in chromatin filament?
Understand the Problem
The question is asking to identify which histone protein is associated with the linker DNA in chromatin filaments. This involves knowledge of molecular biology and the structure of chromatin.
Answer
Histone H1
The histone protein attached to the linker DNA in chromatin filament is Histone H1.
Answer for screen readers
The histone protein attached to the linker DNA in chromatin filament is Histone H1.
More Information
Histone H1, also known as the linker histone, is crucial in organizing the nucleosome structure and helps in the packaging of DNA into chromatin by connecting the entry and exit points of linker DNA on nucleosomes.
Tips
A common mistake is to confuse core histones (H2A, H2B, H3, and H4) with linker histones. However, core histones do not interact with linker DNA.
