Bioinformatics, is related to genetics and genomics, is a science sub discipline that involves using computer technology to collect, store, analyse, and disseminate the biological data and information, such as DNA and amino acid sequences. Scientists and clinicians use databases that organize and index such biological information to increase our understanding of health and disease. Bioinformatics looking  for the pattern within sequences of DNA (or) Protein.

In developmental genetics, research opportunities include the examinations of mechanisms that embryonic and post embryonic development, cell signalling, transcriptional pattering, stem cells , cell differentiation and morphogenesis. These process are studied in model systems for animal and plant development, including drosophila, ascidians and Arabidopsis

Genetic epidemiology is the study of the role of genetic factors in determining the health and diseases in families and in populations and the interplay of such genetic factors with environmental factors. Genetic epidemiology seeks to desire statistical and qualitative analysis of how genetics work in large groups.

Many Genetic disorders results from gene changes that are present in eventually every cell in the body. genes are building blocks of heredity. They are palled from parent to child. Sometimes there is a mutation, a change in genes. The mutation changes the genes instructions for making a protein so that protein does not work properly. This can cause medical condition called genetic disorder. Genetic tests on blood and other tissues can identify genetic disorders.

Human genetics and epigenome analysis of DNA methylation has been added as an extra epigenetic layer. Because epigenetics changes are reversible and do not change their DNA sequence. But they can change how your body reads a DNA sequence, in general high levels of DNA methylation in gene regulatory elements are anti-coated with active genes and chromatin accessibility and they brings out the action as turning genes, controlling the production of protein particular cells.

Regenerative medicine is a broad field that includes tissue engineering but also incorporates research on self-healing where the body uses its own systems, sometimes with help foreign biological material to recreate cells and rebuild tissues and organs. The focus of tissue engineering is resorting, maintaining and improving functions of damaged tissues and organs.
