The whole complement of genes that determine all characteristics of an organism is called genome. Which may be nuclear genome, mitochondrial genome or plastid genome. Genome of many plants contain both functional and non-expressive DNA proteins. Genome project refers to a project in which the whole genome of plant is analysed using sequence analysis and sequence homology with other plants. Such genome projects have so far been undertaken in Chlamydomonas(algae), Arabidopsis thaliana, rice and maize plants. Genome content of an organism is expressed in terms of number of base pairs or in terms of the content of DNA which is expressed as c-value.
