Genomics refers to the study of genome which is the complete set of dna. The blueprint of an organism and includes all its genes. Nucleotide bases a c g and t in a specific order make up the dna sequence of an organism. Human genomes include both protein coding dna genes and non coding dna. Every piece of genomic information sets the pace for detailed studies of the genome.
The human genome is made up of more than 3 billion genetic letters and hence sequencing the genome is a pre requisite to understanding it. Genes are the building blocks of heredity. They are passed from parent to child. Sometimes there is a nucleotide base change mutation in the gene or genes. This mutation in the gene cause a medical condition called genetic disorder. Few of the disorders are down's syndrome thalassemia sickle cell anaemia cystic fibrosis tay sachs etc,
Precision medicine focuses on understanding individual variability in disease prevention care and treatment and also educating the people by providing public with summaries of genetic conditions and their associated genes
Genomics could help identify genetic traits defects in the embryonic stage thus alerting both the prospective parents and doctors about what preventive measures and precautions need to be taken.
