In human body (by the way all life forms except some viruses.) contains DNA in their nucleus. This DNA is made up of Pentose sugars attached to Phosphates in alternate manner and long thread is formed. Such two strands are there in DNA molecule.
To the sugar molecules, you have 4 different types of bases are attached. They are two Purines and two Pyrimidines. Purines are Adenine and Guanine and Pyrimidines are Thymine and Cytosine.
So Adenine get attached to Thymine only and Cytosine is attached to Guanine, only by loose hydrogen bond. So you have to parallel (Actually called 'Anti-parallel, as they have reverse direction.) strands of sugars and phosphate and in between adenine-guanine, guanine-adenine, thymine-cytosine,cytosine-thymine bases.
So you have 4 options in hand and you want 22 codes. One each for 20 amine acid and one each for start and stop signal. So you take next 4 options. It makes 4*4=16 options. Not enough to direct 22 codes. So you take next 4 options. Now you have 4*4*4=64 options. So such three base pairs make a codon. Now Chromosome is made up of 'single' thread of very very long DNA molecule in what is called as double helical structure. Which is bonded in higher animals with a protein called 'Hi-stone'. With start codon gene starts and with stop codon, it stops. In between three is long series of codons which direct 'specific' amine acid. There may be between about 40 to 4000 codons in a single 'gene'. So you have many of them in 'series' in a single chromosome.
You do not know the exact number of genes. But it is some where between 20,000 to 25,000. Together they carry complete information of the individual. (Round worm also have the same number of genes.) But permutations and combinations make all the difference.
You have 23 pairs of chromosomes in every body cell in the 'nucleus'. (You have 100 trillion cells in your body and all of them have same copies of genes in their nucleus and 25 trillion of them are red blood cells, who do not have nucleus in them in adult form and so no genes in them.)

Are genes located on the autosomal called sex linked genes?
No, genes located on the autosomes are not called sex linked genes. Only genes located on the sex chromosomes are called sex linked genes.
Are chromosomes found on genes?
Genes are located on chromosomes and not chromosomes are located on genes. genes are the basic unit of inheritance and they resides on chromosomes.
The father apart two genes are located on a chromosome?
The farthest apart two genes are located on a chromosome the less likely they are to be inherited together. If two genes are on the same chromosome and rarely assort independently the genes are probably located close to each other.
What is the difference between Cells and Genes?
The Cells hold the genes. Genes are a part of DNA, which is located in the Nucleus of a Cell.
Where are genes located and what is the nature of genes?
genes are parts of the cell's DNA genome that encode for specific proteins that are needed in the organism (structural, enzymes, membrane proteins,..) they are located at different places in the genome and the metabolic state of the cell will enchance or repress the transcription of this genes.
Are genes located on the autosomal called sex linked genes?
No, genes located on the autosomes are not called sex linked genes. Only genes located on the sex chromosomes are called sex linked genes.
Are chromosomes found on genes?
Genes are located on chromosomes and not chromosomes are located on genes. genes are the basic unit of inheritance and they resides on chromosomes.
Is genes located in the nuclei on chromosomes?
Genes are located in the nucleus of a cell.
What is located in the nuclei on chromosomes?
it is made up of PROTEINS and DNA MOLECULE, it is located in the nucleus.
Are the chromosomes located in the genes?
No, the genes are in the chromosomes
What located on chromosomes and carry hereditary instructions?
the chromosomes carry the genes
Genes the determiners of heredity are located on the what?
Chromosomes the genes are located on chromosomes in the nucleus of each plant cell.
What do you call the genes that are located on the sex chromosomes?
genes located on sex chromosomes are called sex-linked genes. In humans, there are two types of sex chromosomes: X and Y chromosomes.Genes located on the X chromosome are called X-linked and genes located on the Y chromosome are called Y-linked chromosomes.
Where genes are located on?
on the chromosone
Where can genes be found in the body?
Genes are found on the DNA, which is located in the nucleus.
Where are the genes in the nucleus of the cell?
The genes are located in the chromosomes which are made of DNA.
The father apart two genes are located on a chromosome?
The farthest apart two genes are located on a chromosome the less likely they are to be inherited together. If two genes are on the same chromosome and rarely assort independently the genes are probably located close to each other.
