By What is the relationship between DNA chromatin and chromosomes?
​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 is the relationship between a DNA molecule and a chromosome?
The chromosomes serve as the structure that holds the DNA. The DNA acts as a complete set of instructions that tells our bodies how to develop. Storing more data than any computer, each chromosome contains all the information needed to give you a base for your physical (and emotional) characteristics.
What is the difference between DNA and chromatin?
The DNA is packaged by special proteins called histones to form chromatin. The chromatin further condenses to form chromosomes….

| CHROMATIN | CHROMOSOMES |
| Composed of nucleosomes | They are condensed chromatin fibers |

What is the difference between chromatin and chromosomes?
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 …
Why is it important for DNA to condense into chromosomes?
DNA is tightly packed up to fit in the nucleus of every cell. As shown in the animation, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. Condensing DNA into chromosomes prevents DNA tangling and damage during cell division.
How much DNA is in a chromosome?
One chromosome has 2 strands of DNA in a double helix. But the 2 DNA strands in chromosomes are very, very long. One strand of DNA can be very short – much shorter than even a small chromosome. Strands of DNA are made by joining together the 4 DNA bases in strings.
What is the major difference between chromatin and chromosomes?
Chromatin is a complex formed by histones packaging the DNA double helix. Chromosomes are structures of proteins and nucleic acids found in the living cells and carry genetic material. Chromatin is composed of nucleosomes. Chromosomes are composed of condensed chromatin fibers.
How does a chromatin become a chromosome?
During cell division, chromatin condenses to form chromosomes. Chromosomes are single-stranded groupings of condensed chromatin. During the cell division processes of mitosis and meiosis, chromosomes replicate to ensure that each new daughter cell receives the correct number of chromosomes.
What cell has a single line of chromosomes?
Germ line cells are haploid, which means they contain a single set of chromosomes. In diploid cells, one set of chromosomes is inherited from the individual’s mother, while the second is inherited from the father. Humans have 46 chromosomes in each diploid cell.
What is the difference between DNA chromosomes and genes?
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person’s genes.
