Molecular and Developmental Genetics

Description

A gene is basically a sequence of nucleotides in DNA that is transcribed to produce a functional RNA Developmental Genetics is a branch of genetics that studies how genes control embryonic development. Advances in the field of developmental genetics have emphasized the degree of conservation throughout evolution of the gene control development. There are generally three types of genes namely Type I genes tend to be involved in immune response or sensory receptors while type III genes are involved in cell to cell signaling and type II genes are a complex mix of all three types. A well-known example of gene can be seen in frogs, which usually hatch as a tadpole and metamorphoses to an adult frog, and certain insects which hatch as a larva and then become remodeled to the adult form during a pupa stage. Differential gene expression from genetically identical nuclei creates different types of cell. Differential gene expression can occur at the levels of gene transcription, nuclear RNA processing, mRNA translation, and protein modification. This book of “Molecular and Developmental Genetics” comprises of basic information about genetics and serve as a reference toot to the researchers in genetic developmental biology regenerative medicine and cell biology.
