What is the difference between chromatin and chromosomes

Jan 16, Explanation: Chromatin is the shape a very long and continuous chain of DNA chromosomes take on before mitosis or meiosis. Related questions How do I determine the molecular shape of a molecule? What is the lewis structure for co2? What is the lewis structure for hcn?

Distinctly visible during cell division metaphase, anaphase as highly condensed structures upto several thousand nm. Conformation May have open euchromatin or compact heterochromatin conformations, which is dynamically regulated during the cell-cycle stages.

Predominantly heterochromatic state with a predetermined position in the nucleus and a specific shape such as metacentric, submetacentric, acrocentric, telocentric.

Composed of nucleosomes-a complex of DNA and proteins called histones. Chromatin Fibers are Long and thin. The key difference between histones and nucleosomes is that histones are the proteins that package and order the DNA into nucleosomes while nucleosomes are the basic units of DNA packaging. What makes up the protein component of a nucleosome? One tetramer is composed of two units each of histones H2A and H2B, and the other is composed of two units each of histones H3 and H4.

What is the purpose of nucleosomes? Nucleosomes are made up of DNA wrapped around histone complexes in a pattern that is universal in eukaryotic cells. They apparently function to reduce the overall length of DNA in the nucleus, thus helping to keep the chromatin organized.

Therefore, meiosis results in four haploid genetically unique daughter cells, each with half the DNA of the parent cell Figure below. In human cells, the parent cell has 46 chromosomes 23 pairs , so the cells produced by meiosis have 23 chromosomes.

These cells will become gametes. It is commonly accepted that the loop domain represents the basic structural unit of eukaryotic chromatin associated with DNA replication, gene expression and higher order packaging. Each individual nucleosome core particle consists of a complex of eight histone proteins- two molecules each of histones H2A ….. The histone octamer forms a protein core around which the double-stranded DNA is wound. Begin typing your search term above and press enter to search.
