Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell’s genetic instructions. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus.
What is chromatin or chromosomes?
Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. … Under the microscope in its extended form, chromatin looks like beads on a string. The beads are called nucleosomes. Each nucleosome is composed of DNA wrapped around eight proteins called histones.
What is the major difference between chromatin and chromosomes?
Chromatin is a complex formed by histones packaging the DNA double helix. Chromosomes are structures of proteins and nucleic acids found in the living cells and carry genetic material. Chromatin is composed of nucleosomes. Chromosomes are composed of condensed chromatin fibers.
What is difference between chromatin Fibre and chromosomes?
The chromatin further condenses to form chromosomes.
|Difference between Chromosomes and Chromatin|
|Composed of nucleosomes||They are condensed chromatin fibers|
|Visualized under electron microscope||Visualised under light microscope|
|Thin, long, uncoiled structure||Thick, compact, ribbon-like structure|
What are chromosomes made of?
Chromosomes are made up of a DNA-protein complex called chromatin that is organized into subunits called nucleosomes.
