Where and when can I find chromatin?

What is chromatin and when is it present?

​Chromatin

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.

Why chromatin is found only in eukaryotes?

Chromatin is only found in eukaryotic cells, with prokaryotic cells having a different arrangement of their genetic material called a genophore – a chromosome that doesn’t contain chromatin.

Is chromatin found in plants or animals?

Chromatin is found in both plant and animal cells. The major difference between plant and animal cells is that plant cells have a cell wall and chloroplasts.

What is a chromatin state?

In the more general sense, the “chromatin state” of a genomic region can refer to the set of chromatin-associated proteins and histone modifications in that region. These are most often assayed by ChIP-seq, but also ATAC-seq, DNase-seq, ChIP-exo, and other methods.

Is chromatin found in prokaryotic cells?

Eukaryotic chromosomes are composed of chromatin, and each consists of two complementary strands of DNA coiled tightly around histones. The structure of chromatin is scaffolded, with three distinct levels.

Eukaryotic chromosome.

Location Nucleus Nucleoid (region in cytoplasm)

What do chromosomes and chromatin have in common?

Chromosomes, chromatids, and chromatin share some of the same components. All three have DNA and histone proteins. All three are involved in the process of mitosis as cells divide.
