If a mutation made histone proteins bind less tightly to DNA how might the cell cycle be affected?

So if the histones are not properly binding to the DNA then the DNA will not be able to condense into chromosomes, which it needs to do for mitosis to occur. So basically, mitosis will not occur.

What is the role of proteins in allowing DNA to fit in a cell?
The protein histone, and attendant proteins, spool the DNA tightly around their complexes and then further wind these complexes into tighter and tighter shapes. About two meters worth of DNA per cell is held in these histone complexes.
The constricted region holding two chromatids together is called a histone?
Sounds more like a centromere. Histones are proteins which are responsible for coiling the DNA up tightly.
What is DNA tightly wrapped around?
The protein histone primarily.
How do chromosomes turn into DNA?
Replication chemicals trigger during cell replication trigger DNA to wrap tightly around histone octamers (histone proteins) to create nucleosomes, for DNA synthesis. This happens during the prophase stage of cell replication.
What are strands of DNA wound around?
DNA coils around proteins called histones.
In eukaryotic chromosomes DNA is tightly coiled around proteins called?
The "beads on a string" are called nucleosomes.

Eukaryotic chromosomes contain both DNA and protein tightly packed together to form a substance called?
The complex of both histone and non-histone chromosomal proteins and DNA is known as chromatin.

What role do proteins play in enabling the enormous amount of DNA in a eukaryotic cell to lit into the nucleus and what are those proteins called?
Histones are proteins which help to tightly pack the DNA into the nucleus of eukaryotic cells. A histone octamer (8 histones together= 2 of H3, 2 of H4, 2 of H2A and 2 of H2B) is formed and the DNA is wrapped 1.65 times around these 8 tightly packed histones forming a nucleosome. There are many nucleosomes along the DNA and together they look similar to a pearl necklace, with the beads being the nucleosomes. The nucleosomes can then be packed together even more tightly (like in heterochromatin) by other proteins.Histones
What are strands of DNA wound around?
DNA coils around proteins called histones.
What consists of DNA tightly coiled around proteins?
Chromosomes
What is chromosome and what does it do?
A chromosome is a mix of tightly packed DNA and proteins.
Abe is a technician instructed to photograph some chromatids How would he distinguish a chromatid from a chromosome?
Chromatids would be long strings of genetic material not that easy to see under a microscope. A chromosome is bulky, as it is condensed DNA wrapped tightly around histone proteins. Chromatids are wrapped around histones too, but loosely.
