What is the root word of chromatin?

Etymology. Borrowed from German Chromatin, from (combining form of) Ancient Greek χρῶμα (khrôma, “colour”) + -in.

What is the root of the word chromosome?

The word chromosome was originally coined in German from the Greek words khroma, meaning “color,” and soma meaning “body.” In the late 1800s, a scientist, Wilhelm von Waldeyer-Hartz, gave chromosomes their name because chromosomes easily accept dye and take on patterns of light and dark when exposed to different stains …

What is chromatin medical term?

Medical Definition of chromatin

: a complex of a nucleic acid with basic proteins (as histone) in eukaryotic cells that is usually dispersed in the interphase nucleus and condensed into chromosomes in mitosis and meiosis. Other Words from chromatin.

How did chromatin get its name?

Chromatin was named by Walther Flemming in 1882 who examined cells using a light microscope. Flemming found that in cells stained with a basic dye, the granular material in the nucleus turned a bright color. They named this material “chromatin,” using the Greek word chroma, which means color.

What cytoplasm means?

cytoplasm, the semifluid substance of a cell that is external to the nuclear membrane and internal to the cellular membrane, sometimes described as the nonnuclear content of protoplasm. In eukaryotes (i.e., cells having a nucleus), the cytoplasm contains all of the organelles.

Is Gene a root word?

The root word gene comes from the Greek genea, which means “generation or race.” The word genus had been used since the 1550’s as a scientific division, and in late 19th Century Germany, the word genotypus was coined to go along with early studies of genetics.

Where is the chromatin located?

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

What is chromatin name two components of chromatin?

The two main components of chromatin are DNA and histones.

What is a chromatin in biology quizlet?

chromatin. The complex of DNA and proteins that makes up eukaryotic chromosomes. When the cell is not dividing, chromatin exists in its dispersed form, as a mass of very long, thin fibers that are not visible with a light microscope.

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”).

How chromatin is formed?

Prophase: During prophase of mitosis, chromatin fibers become coiled into chromosomes. Each replicated chromosome consists of two chromatids joined at a centromere. … Each cell has the same number of chromosomes. The chromosomes continue to uncoil and elongate, forming chromatin.

What is chromatin vs chromosome?

The main difference between chromatin and chromosome is that chromatin consists of the unravelled condensed structure of DNA for the purpose of packaging into the nucleus whereas chromosome consists of the highest condensed structure of the DNA doublehelix for the proper separation of the genetic material between …

What are in chromosomes?

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

What is in the nucleolus?

The nucleolus is composed of DNA, rRNA and ribosomal proteins. A eukaryotic cell without a nucleolus will lose the ability to synthesize proteins. As the two ribosomal subunits exit the nucleus through the nuclear pore, the subunits associate to form a functional ribosome.

What is in the Nucleoplasm?

The nucleoplasm has a complex chemical composition, it is composed mainly of the nuclear proteins but it also contains other inorganic and organic substances such as nucleic acids, proteins, enzymes and minerals. … The nucleoplasm contains many enzymes which are necessary for the synthesis of the DNA and RNA.
