Is a DNA-protein complex that makes up eukaryotic chromosomes quizlet?

The DNA- protein complex found within eukaryotic chromosomes is termed chromatin.

What are the parts that make up the DNA eukaryotic chromosome?

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. First, the DNA is wrapped around clusters of histones, forming nucleosomes that are connected by linker DNA.

What is defined as a complex of DNA and proteins that makes up the cell’s chromosomes quizlet?

Chromatin. The complex of DNA and proteins that makes up a eukaryotic chromosome.

What is the complex of DNA and histone proteins in eukaryotes called?

The answer to this question lies in the fact that certain proteins compact chromosomal DNA into the microscopic space of the eukaryotic nucleus. These proteins are called histones, and the resulting DNA-protein complex is called chromatin.

What are eukaryotic chromosomes made of quizlet?

Eukaryotic chromosomes are composed of chromatin, a complex of DNA and associated proteins. In fact, most eukaryotic chromosomes are about 60% protein and 40% DNA. A significant amount of RNA is also associated with chromosomes, because the chromosome is the site of RNA synthesis within the cell.

What is the term for this DNA-protein complex quizlet?

STUDY. DNA is found in association with proteins within the cell. What is the term for this DNA-protein complex? chromatin.

What makes up a eukaryotic chromosome?

Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear proteins called histones. Humans inherit one set of chromosomes from their mother and a second set from their father.

Where is DNA in eukaryotic cells?

the nucleus
In eukaryotes, the cell’s genetic material, or DNA, is contained within an organelle called the nucleus, where it is organized in long molecules called chromosomes.

Which best describes how DNA is packaged in a eukaryotic chromosome?

Eukaryotes, whose chromosomes each consist of a linear DNA molecule, employ a different type of packing strategy to fit their DNA inside the nucleus (Figure 2). At the most basic level, DNA is wrapped around proteins known as histones to form structures called nucleosomes.

What is meant by term nucleosome?

A nucleosome is a section of DNA that is wrapped around a core of proteins. Inside the nucleus, DNA forms a complex with proteins called chromatin, which allows the DNA to be condensed into a smaller volume. When the chromatin is extended and viewed under a microscope, the structure resembles beads on a string.

What is the name for the collection of DNA in the nucleus of eukaryotic cells?

The name for the collection of DNA in the nucleus of eukaryotic cells is chromatin. Chromatin is composed of DNA and protein. Within the a chromosome, a densely packed string of DNA is coiled around protein molecules called histones.

How is DNA packaged up in eukaryotes?

In eukaryotes, however, genetic material is housed in the nucleus and tightly packaged into linear chromosomes. Chromosomes are made up of a DNA-protein complex called chromatin that is organized into subunits called nucleosomes.

Which of the following macromolecules make up eukaryotic chromosomes?

The correct answer is A. Each chromosome in a eukaryotic cell is made up of DNA which is coiled and condensed around an octamer of basic proteins called histones.

What are the defining features of eukaryotic chromosomes?

Eukaryotes have [1] a membrane-bound nucleus, [2] intracellular organelles, and [3] a cytoskeleton • Most eukaryotes undergo sexual reproduction •The genome size of eukaryotes spans a wider range than that of most prokaryotes • Eukaryotic genomes have a lower density of genes • Prokaryotes are haploid; eukaryotes have …

What is the term for this DNA protein complex?

This DNA-protein complex is called chromatin, wherein the mass of protein and nucleic acid is nearly equal. Within cells, chromatin usually folds into characteristic formations called chromosomes. Each chromosome contains a single double-stranded piece of DNA along with the aforementioned packaging proteins.

What is the name of the protein that eukaryotic DNA is wrapped around to form nucleosomes quizlet?

In eukaryotes, DNA is wrapped around proteins to create a structure called chromatin.

Is histone a protein?

A type of protein found in chromosomes. Histones bind to DNA, help give chromosomes their shape, and help control the activity of genes.

Where and what form is eukaryotic DNA found?

Where and in what form is eukaryotic DNA found? It’s found in the cell nucleus of a eukaryotic cell as chromosomes.

What does a eukaryotic cell contain?

eukaryote, any cell or organism that possesses a clearly defined nucleus. The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes (bodies containing the hereditary material) are located.

What are genes histone and nucleosomes?

The nucleosome is the fundamental subunit of chromatin. Each nucleosome is composed of a little less than two turns of DNA wrapped around a set of eight proteins called histones, which are known as a histone octamer. Each histone octamer is composed of two copies each of the histone proteins H2A, H2B, H3, and H4.

What are the components of a duplicated chromosome?

In a duplicated chromosome, the region on each sister chromatid where they are most closely attached to each other by proteins that bind to specific DNA sequences; this close attachment causes a constriction in the condensed chromosome. chromatin. The complex of DNA and proteins that makes up eukaryotic chromosomes.

What is chromatin in biology?

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. A cellular structure carrying genetic material, found in the nucleus of eukaryotic cells.

What is the structure of a bacterial chromosome?

(A bacterial chromosome usually consists of a single circular DNA molecule and associated proteins. It is found in the nucleoid region, which is not membrane bounded.)

What happens to chromatin when the cell is not dividing?

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. A cellular structure carrying genetic material, found in the nucleus of eukaryotic cells.
