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>
Biology.
The science of biology is a systematic and organized body of delving into and about life.
Anything that has life.
Studying life, animals, plants, protists and the interactions.
A biological system<span> or also called, a biotic community is composed mainly of living organisms. These organisms can be classified into the main layman categories of animals and plants, majorly. These creatures can be more furthered classified by how they eat and survive. Plants can make their own food through, photosynthesis. Animals eat and are dependent. Can be classified into subtypes as: herbivores, omnivores and carnivores. What makes all of these organisms a biotic community or a biological system is they contain cells, cells are the basic unit and foundation of every living thing. </span>
Answer:
At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.
hope this helps
have a good day :)
Explanation:
Glial cells. More specifically, it could be oligondenrocytes, astrocytes, ependymal cells, schwann cells, microglia, or satellite cells, because they are all types of Glial cells.
