What is the primary function of histones in the nucleus of a cell?
A
To regulate the passage of ions across the nuclear membrane
B
To package DNA into structural units called nucleosomes
C
To synthesize ribosomal RNA
D
To facilitate the transport of RNA out of the nucleus
Verified step by step guidance1
Understand that histones are proteins found in the nucleus of eukaryotic cells.
Recognize that the primary role of histones is related to DNA packaging.
Learn that histones help in organizing DNA into structural units called nucleosomes, which are essential for DNA compaction.
Note that nucleosomes consist of DNA wrapped around a core of histone proteins, allowing efficient packaging within the nucleus.
Acknowledge that this packaging is crucial for DNA stability and regulation of gene expression.
