Question

Genes and chromosomes have similar behaviour.

Answer 1

A chromosome is an organized structure of DNA and protein found in the nucleus of cells. It is a single piece of coiled DNA containing many genes. These are considered to be the vehicles of heredity as they carry genes. Genes are small points on the chromosome responsible for one character of an individual.

Genes are particular loci on the chromosomes which are responsible for particular traits of an individual. Genes carry the genetic information in the form of DNA which can be transcribed and translated into particular protein required by the cell. Each gene contains a particular set of instructions, coding for a particular protein.

Similarities between genes and chromosomes
*Genes occur in pairs at the same location on the different homologous chromosomes. These are called as alleles of a gene.Chromosomes occur in pairs called as homologous chromosomes.
*Genes are responsible for carrying the characteristics of individuals. Chromosomes act as vehicles of inheritance.
*Both genes and chromosomes are made up of DNA.
*Genes are found on the chromosomes and chromosomes are found in the nucleus. So, both are found inside the nucleus.
