Explain why DNA requires structural robust and efficient storage and organization mechanisms/structures.
wel

Answer:

DNA packaging contributes to the compaction of the genetic material into cells that are many times smaller and also regulates gene expression and cell replication in living systems.

Explanation:

DNA is a fundamental molecule that contains instructions that make each organism unique. Each chromosome is composed of a very long linear DNA molecule associated with histone proteins that compact the genetic material, which is known as DNA packaging. Transcription and replication require that both strands of the DNA separate. Nonetheless, during DNA packaging, nucleosomes and the folding into chromatin fibers ensure chromosomal DNA is correctly packaged inside smaller nuclei. In consequence, DNA packaging not only enables the compaction of long linear DNA into the cells but also is involved in key biological processes such as gene regulation (transcription) and cell replication.
