Question: What is the word that is used to describe chromatin?

chromatin. / (ˈkrəʊmətɪn) / noun. cytology the part of the nucleus that consists of DNA and proteins, forms the chromosomes, and stains with basic dyesSee also euchromatin, heterochromatin.

How do you describe 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.

What can chromatin be defined as?

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 best definition of chromatin?

Chromatin (biology definition): A substance made up of DNA or RNA and proteins, such as histones. It condenses during cell division (mitosis or meiosis) and becomes a chromosome. Chromatins are “unwound” condensed structures whereas chromosomes are highly packaged and more condensed than chromatins.

What does chromatin mean in Greek?

Chromatin was discovered by Walther Flemming in the 1880s, who noticed that the dense nucleic substance greatly absorbed certain dyes (hence the name “chromatin,” which derives from the Greek root “chroma” meaning “color”).

What is a chromatin quizlet?

Chromatin. -Genetic material in a non-dividing cell. -the material of which the chromosomes of organisms are composed. It consists of protein, RNA, and DNA. -Unwound DNA.

What is chromatin name two components of chromatin?

The two main components of chromatin are DNA and histones.

What is a chromatin where do they resemble the chromosomes?

Within cells, chromatin usually folds into characteristic formations called chromosomes. … 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.

What are chromatin Fibres?

Chromatin fibers are coiled and condensed to form chromosomes. Chromatin makes it possible for a number of cell processes to occur including DNA replication, transcription, DNA repair, genetic recombination, and cell division. Chromatin, Chromosomes and Chromatids.

What is a chromatin kid definition?

Kids Encyclopedia Facts. Chromatin is the complex combination of DNA and proteins that makes up chromosomes. It is found inside the nuclei of eukaryotic cells. Chromatin is divided into heterochromatin (condensed) and euchromatin (extended) forms. Heterochromatin is composed mostly of satellite DNA tandem repeats.

How is chromatin made?

Chromatin is a mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division. … The nucleosome is further folded to produce a chromatin fiber. Chromatin fibers are coiled and condensed to form chromosomes.

What is the basic structure of the chromatin?

The basic structure of chromatin—either heterochromatin or euchromatin—is called the nucleosome. The nucleosome is a complex of 146 base pairs of DNA, wound in two turns around the outside of a disk‐like complex of eight proteins (called histones).

What is chromatin when is it observed clearly?

Chromatin is a complex of DNA and protein found in eukaryotic cells. 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.
