Marine climate tend to has <span>warm winters and cool summers.
Regions with marine climate mostly located in a region with low elevation. Regions with low elevation tend to have higher temperature, but the existence of water near that region even out the temperature which resulted in moderate level of temperature all year long.</span>
The addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes because they help to condense it into chromatin.
<h3>What is the relationship between histones and DNA?</h3>
Histones are a family of basic proteins that associate with DNA in the nucleus and help to condense it into chromatin. Nuclear DNA does not appear on free linear strands; it is highly condensed and involves histones to fit inside the nucleus and participate in the formation of chromosomes.
<h3>How does DNA compact with histones?</h3>
Each chromosome is made up of a single molecule of double-stranded DNA wrapped around histones, the nucleosome. This fiber rewinds into a second level of compression, known as the solenoid. Most of the time, cells keep the DNA compacted in the selenoid loops attached to the chromosomal backbone.
Whit this information, we can conclude that the addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes because they help to condense it into chromatin.

∙
Mitotic cell division starts with the condensing of chromosome accompanied by splitting of the centrosome and its movement towards the opposite poles.
∙
As the nuclear envelope and nucleolus disappear, spindle fibres arise from the centrosomes and start binding to the condensed chromosomes at the centromeres.
∙
The chromosomes bound by the spindle fibers are then arranged in the middle of the cell forming the equatorial metaphase plate.
∙
Next the centromere splits and the sister chromatids are pulled away towards the poles by the contraction of spindle fibres.
∙
Following this, a cleavage furrow starts to develop in the middle of the cell while the nuclear membrane starts to reappear around the separated chromatids.
∙
The condensed chromatids start thinning into chromatin fibre along with reappearance of the nucleolus and the cleavage furrow deepening further.
∙
Finally as the nuclear membrane becomes fully intact, the cleavage furrow deepens and split the cells from middle into two daughter cells.
