Dear student,

Cellular DNA is the information source for making proteins in cell. Genes are functional segments of DNA and each gene is associated with synthesis of a single protein.

 These proteins could act as hormones or some may be enzymes. Depending on the amounts of these proteins produced, a particular characteristicor trait is expressed and controlled.

Example - Plant height depends on the amount of a particular growth hormone produced.  The amount of the plant hormone made will depend on the efficiency of the process for making it.
