Question

difference between gene and chromosomes...

Answer 1

Basically gene is a segment of DNA and a chromosome contains many genes.
A gene is segment of DNA which can code for a single protein, polypeptide or more than one polypeptide. But the DNA is typically too long to accomodate in a cell. Hence it needs to be coiled, supercoiled! The supercoiling of DNA leads to the formation of chromatin material (in eukaryotes) with the help of different protiens. At the time of cell division this chromatin condemses further to give rise chromosomes for duplication and segregation.

Answer 2

chromosome is thread like structure usually present in nucleus . it is made up of DNA and proteins.it contain hereditary information in form of genes .
gene: it is inhereditary charactor from one generation of other generation.
