Molecular biology is the study of the function and structure systems of molecular science. They deal with RNA (Ribo Nucleic acid), DNA (Deoxyribo nucleic acid), proteins, stem cells their structure and mechanism. They clone animal cells, plant cells to produce new variety of animal and plants. They take help of biotechnology and use them in new research methods. They also use micro organisms cells in their research and depend on the specialization they develop solutions to solve problems like cancer, and some other disease. They involve in developing animal cells, gene regulation in microbial cells and many more. This is the career for the one who loves research on microbial science.
