Each long string of DNA winds around structural protein spools called 'histones' to form a material called 'chromatin'. The chromatin further loops and coils to form the tightly condensed chromosome structure. This tight packing is important in making sure these long strings of DNA can fit inside the cell's nucleus.

In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope.
How is DNA arranged into chromosomes?
DNA is organized into 46 chromosomes including sex chromosomes, 3D animation The millions of bases, which make up the human genome are organized into structures called chromosomes. These are arrangedinto 22 matching pairs plus 1 pair of sex chromosomes consisting of 2 X's in women and an X and a Y in men.
What is the name of the material that forms the chromosomes?
Each long string of DNA winds around structural protein spools called 'histones' to form a material called 'chromatin '. The chromatin further loops and coils to form the tightly condensed chromosome structure. Click to see full answer.
What is DNA made of?
What is DNA made up of? DNA structure DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).
What is the structure of DNA in a cell?
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
What does a chromatin look like?
Usually if a cell is observed without treatment and at a non-specific stage we get to see chromatin.It looks like a tangled skein of fibre. Chromosomes are composed of DNA and histones.
What are the segments of DNA that encode the order of amino acids in proteins?
Genes are segments of DNA that encode the order of amino acids in proteins. DNA chromosomes and genes are very closely related.

· Genes contain DNA (deoxyribonucleic acid). DNA is the chemical basis of heredity. Think of it this way: DNA is in genes, genes are on chromosomes. When "mapping" all genes on all human chromosomes was first seriously conceived, it was called the Human Genome Project - a combination of gene and chromosome.

The chromatin material condenses to form chromosomes during cell division. Chromosomes are composed of DNA and protein. DNA molecules contain the information necessary for constructing and organising cells. Functional segments of DNA are called genes. A chromosome consists of two identical and spirally coiled threads called sister chromatids.

Chromatin= uncoiled DNA Chromosome = coiled DNA You have 46 chromosomes or 23 pairs in the nucleus of each body cell. o 23 from mom and 23 from dad Gene = a segment of DNA that codes for a protein, which in turn codes for a trait (skin tone, eye color, etc); a gene is a stretch of DNA. o There is a gene for every protein your body has to make.

Correct option is D) Chromatin fibers are made from coiling of a long polynucleotide strand of DNA to fit into the cell. Chromatin is present as a diffuse network of fine filaments in the non dividing nucleus. At the time of cell division, chromatin material becomes condensed into rod-like structures called as chromosomes. Each chromosome has a centromere and two arms called …

Chromatin and chromosome are related to each other. They are different levels of DNA arrangements. All chromosomes have chromatin. Chromatin is a nucleoprotein complex that plays important role in the transfer of genetic material that is folded into compact chromosome. This article will provide 5 important insights regarding chromosomes and chromatin.
