chromatin labelled diagram simple and easy ..
Answers
Explanation:
The structure of chromatin or the so-called nucleosomes resembles the arrangement of string on beads when observed under the light microscope in its elongated method. Each nucleosome comprises DNA, which is wrapped with eight proteins termed histones. Later, these nucleosomes are enfolded into 30 nm coiled named solenoid. Therefore the presence of histone proteins helps in supporting the chromatin structure.
Explanation:
Chromatin is a complex of DNA and protein found in eukaryotic cells.[1] Its primary function is packaging long DNA molecules into more compact, denser structures. This prevents the strands from becoming tangled and also plays important roles in reinforcing the DNA during cell division, preventing DNA damage, and regulating gene expression and DNA replication. During mitosis and meiosis, chromatin facilitates proper segregation of the chromosomes in anaphase; the characteristic shapes of chromosomes visible during this stage are the result of DNA being coiled into highly condensed chromatin.
