DNA is condensed by a certain amount just on its own, just by its own interactions within the DNA molecule,..but whne proteins get involved it gets condensed 30000 fold
<span>what happens is that proteins called histones are like hockey pucks, and DNA wraps around it 1.5 times and then goes to another histone and wraps around that so that it looks like beads on a string (i hope that makes sense, its the only way to describe it) </span>
<span>these histones condense this DNA a lot, and when the histones get methylated then the DNA packs together even closer to get heterochromatin (VERY densely packed DNA)...the theory here is that DNA has a net negative charge due to the phosphate groups in the DNA backbone and doesnt allow the DNA to come together as closely as it could (like charges repel like charges), but when histones are methylated, the negative charge on the DNA is masked by the methyl groups and DNA can come together closer </span>
When someone moves to a place of higher education, financial issues are usually a big factor. Can they afford it? Is there ways help lower costs? Are they eligible for scholarships? Would they make enough to pay any student loans they may take? People also need to worry about if they have enough for a place to stay while in school, they also need to look at transportation. All of these factors are things that involve finance

Cellular respiration is the process by which glucose is broken down to carbon dioxide and water in the cell.
Cellular respiration refers to the process in which glucose is broken down to produce energy. The reaction of cellular respiration is; C6H12O6 -----> 6H20 + 6CO2. This process occurs in the mitochondria of the cell which is within the cytoplasm. In times of oxygen deficit, lactate or ethanol may be produced by the process.
The following statements are true about cellular respiration;
- the reactions happen in the cytoplasm
