In the most basic terms, genome is the genetic material of an organism. It is what tells the organism what to be and how to be. The genome is coded in DNA, or in RNA for many types of viruses. The term, genome, was coined in the 1920, as a portmanteau of gene and chromosome.
Therefore, a gene or set of genes determines the differences between individuals within a species as well as differences between species. Human genome consists of over 20,000 genes, and certain genes of humans are also found in other animals and even in certain plants.herefore, the amount of genes is higher than that of DNA of a single cell. â¢ Genes determine one or few traits while DNA determines many traits. â¢ When the DNA replicates, genes also replicate with it.
