Quick Answer: When can chromatin be found?

During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible.

Where and when can I find chromatin?

Chromatin is a complex of macromolecules composed of DNA, RNA, and protein, which is found inside the nucleus of eukaryotic cells.

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 does chromatin look like?

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 it called when chromosomes appear?

prophase. a cell division begins, the chromatin threads coil and shorten so that visible bar like bodies (chromosomes) appear.

Does chromatin have RNA?

Whether RNA itself plays a direct structural role in chromatin is, however, not known. Here, we report results indicating that RNA plays a general structural role in eukaryotic chromatin. Our results indicate that purified chromatin contains significant amounts of RNA (2%–5% of total nucleic acids).

How much chromatin is in a chromosome?

Explanation: So there is one chromatin per one chromosome. This tight packing is important in making sure this long string of DNA can fit inside the cell’s nucleus.

How many pieces of chromatin are in human cells?

Human diploid cells have 46 pieces of chromatin.
