A chromosome is very tightly packed DNA. DNA stores the information that is used to synthesize proteins. Thus the entire makeup and organization of an organism relies on the information stored in the chromosomes.
DNA becomes wrapped around proteins known as histones. 8 histones form a structure known as a nucleosome. Multiple nucleosomes condense together with the addition of another histone, H1 to form a 30 nanometer fiber. Scaffolding proteins further pack the 30 nanometer fiber into a chromosome.

Where is it possible to learn about the functions of the chromosome?
The functions of a chromosome are complex, and so the available resources detailing such functions are quite numerous. For individuals looking for overviews of the chromosome, Wikipedia is a good source. For those looking for in-depth information and the latest findings, PubMed is a good starting point.
What do genes on the same chromosome do?
code of different functions =)
What is the chromosome that dictate most body characteristics?
The chromosome that dictates most body characteristics is chromosome 1. It is the largest chromosome in humans and carries a significant amount of genetic information related to various traits and functions in the body.
Where did you get your chromosome?
one of your parents each give a chromosome
Can you live with a y-chromosome and no x-chromosome?
No. The human X chromosome contains over 1000 genes, many of which are essential for life. The Y chromosome in comparison has only about 120 genes. A zygote with Y0 or YY (one or two Y chromosomes) would not be viable.
What is the 22 chromosome called?
The 22nd chromosome is called the autosomal chromosome, as it is one of the non-sex chromosomes found in humans. Each cell typically contains two copies of chromosome 22, one inherited from each parent. It contains around 500 to 800 genes involved in various biological functions.
What is a chromosome compared to in a factory?
A chromosome in a cell is like a blueprint in a factory. It contains the instructions (genes) that determine the characteristics and functions of the organism, similar to how a blueprint guides the construction and operation of a factory.
Why chromosomes are important for organisms?
each chromosome has thousands of genes that play an important role in determining how an organism develops and functions
Why are there very few genes on the y chromosome?
The Y chromosome contains fewer genes primarily because it has undergone significant degeneration over evolutionary time. It lost many of its original genes, particularly those that are not essential for male-specific functions, as it paired with the X chromosome during evolution. Additionally, the Y chromosome is largely composed of repetitive sequences and heterochromatin, which further limits gene content. This specialization has led to a focused role in male sex determination and spermatogenesis rather than a broad range of functions.
A chromosome contains many genes that are transcribed into different what?
A chromosome contains many genes that are transcribed into different RNA molecules. These RNA molecules can serve as templates for protein synthesis or have other functions in the cell.
What is it called when extra copies of part of a chromosome are made?
It is called gene duplication when extra copies of a gene or segment of DNA are created within a chromosome. This process can lead to genetic variation and the emergence of new gene functions.
What is X chromosome?
The x chromosome is one of the sex chromosomes, the other being the y chromosome. In mammals there are two of the sex chromosomes in each organism. Females generally contain two x chromosomes, and males contain one x chromosome and one y chromosome.
