1 The other 22 pairs are autosomes (non-sex chromosomes) and look the same for both males and females. 2  The DNA making up each of our chromosomes contains thousands of genes. 3  At the ends of each of our chromosomes are sections of DNA called telomeres.
The resulting bundle is called a chromosome. A Gene is a particular section of the chromosome's DNA string. There are many such sections on the DNA string-thus it contains (also calls 'codes') many genes-in humans between 500 and 4500 depending on what chromosome.One gene contains information for producing one particular protein.
