In the nucleus of each cell, the DNA molecule (which determines traits) 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. Chromosomes are not always visible because they usually are uncoiled inside the nucleus as loose strands called chromatin. When it is time for the cell toperform meiosis or mitosis, they condense and wrap up tightly. The tightly wound DNA is the chromosome (3). Most of what researchers know about chromosomes was learned by observing chromosomes during cell division (1).
your welcome :) have a nice day!

What are the importance of chromosomes?
chromosomes are filamentous structures which are present in the nucleus as chromatin reticulum and are visible only during cell division..this is what i know about choromos..lol
What is the importance of producing haploid egg and sperm cells at the end of meiosis?
It is important because the gamete needs to have 46 chromosomes or 23 pairs. If the sperm and egg both contributed 46 chromosomes, then the cell would have 92 chromosomes.
What discovery in the 1900 supported Mendel's ideas?
Chromosomes
How is Eukaryotic DNA organized?
they are grouped into multiple chromosomes.
How do autosomal chromosomes differ from chromosomes?
Autosomal chromosomes are all non-sex (X or Y) chromosomes.
What is the importance about chromosomes in pregnancy?
Chromosomes decide the gender of the child.
What are the importance of chromosomes?
chromosomes are filamentous structures which are present in the nucleus as chromatin reticulum and are visible only during cell division..this is what i know about choromos..lol
What is the importance of chromosomes in nucleus?
The overall importance of chromosomes is that they contain genetic information, DNA, which is used as a plan to create every component of the human body. Generally speaking, DNA codes for all genes and regulatory elements. Essentiallly, chromosomes carry the instructions for new cell creation, cell division, and how every minute detail should be.
What is the importance of producing haploid egg and sperm cells at the end of meiosis?
It is important because the gamete needs to have 46 chromosomes or 23 pairs. If the sperm and egg both contributed 46 chromosomes, then the cell would have 92 chromosomes.
Explain the importance of crossing-over during the first division of meiosis?
The first division reduces the number of Chromosomes by half.
What is the importance of meiosis in heredity and natural selection?
this is where the genes are mixed up, and it allows genes to be exchanged across chromosomes and randomizes the assortment of chromosomes to the offspring.
What discovery in the 1900 supported Mendel's ideas?
Chromosomes
What is the importance of the random alignment of homologous pairs in Metaphase 1?
The random alignment of homologous pairs of chromosomes during Metaphase 1 allows for independent assortment of genes.
What has the author R G Beilharz written?
R. G. Beilharz has written: 'The importance of the sex-chromosome in quantitative inheritance' -- subject(s): Heredity, Sex chromosomes
All chromosomes except the X and Y sex chromosomes are called?
homologous chromosomes and autosomal chromosomes
Humans are a diploid species what does this say about their chromosomes?
They have homologous chromosomes
What best describes chromosomes that contain genes for the same characteristics?
Chromosomes that have the same sequence of genes are called homologous chromosomes.
