How many chromatin do cells have?

Do cells have chromatin?

Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around nuclear proteins in order to fit inside the nucleus. Chromatin exists in two forms.

How many strands of chromatin do human cells have?

A chromosome is a double strand of DNA. Humans have 46 chromosomes. Chromatin is a complex of DNA, proteins (mostly histones), and RNA. Chromatin – Wikipedia There would be 46 chromatins in a human cell, one for each chromosome.

Is chromatin a prokaryote?

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.

Eukaryotic Chromosome Prokaryotic Chromosome
Location Nucleus Nucleoid (region in cytoplasm)

Why chromatin is found only in eukaryotes?

Interestingly, chromatin not only serves as a way to condense DNA within the cellular nucleus, but also as a way to control how that DNA is used. In particular, within eukaryotes, specific genes are not expressed unless they can be accessed by RNA polymerase and proteins known as transcription factors.

What is the difference between DNA and chromatin?

The DNA is packaged by special proteins called histones to form chromatin. The chromatin further condenses to form chromosomes.
