Biology is the study of living things. Biology also includes the study of humans at the molecular, cellular. If the focus of investigation is the application of biological knowledge to human health, the study is often termed biomedicine. Molecular Biology is the research that seeks to understand the molecular basis of life.
In particular it relates the structure of specific molecules of biological importance-such as proteins, he nucleic acids DNA and RNA, and enzymes, to their functional role in the intact cell and organism. There are many branches of biology. Some of them are: Zoologists, botanists, entomologist and microbiologist. Zoologists are concerned with animals and botanists with plants. Entomologist’s study insects while a microbiologist works with living things that are too small to see without help of a microscope.
