Finding a good research area is quite a challenging task. A topic should be attention-grabbing, relevant, interesting to academic community and you personally. It is necessary to analyze recent discoveries, controversial issues to formulate a valuable idea and make a scientific contribution. This article should give you inspiration because we have collected the best topics from several biology branches, good issues for presentations and academic projects. Pick up one of them or use examples to come up with your own option.

Molecular biology topics

molecular biology topics

Molecular biology is a science aiming to understand the nature of life phenomena by studying biological objects and systems at a molecular level. Its ultimate goal is to find out how and to what extent characteristic life manifestations, such as heredity, self-reproduction, protein biosynthesis, excitability, growth and development, information storage and transmission, energy transformations, mobility, are stipulated by molecular structure, properties and interaction in biologically important substances, primarily in the two main classes of high molecular weight biopolymers - proteins and nucleic acids.

Molecular biology is a new natural science area closely related to long-established research fields that are covered by biochemistry, biophysics, and bioorganic chemistry. Here are some interesting biology topics from this category:

  • The main molecular biology development stages
  • Tasks and methods of molecular biology

Cell biology topics

In a multicellular organism, all complex life manifestations arise as a result of its constituent cells’ coordinated activity. Cells are the smallest units of living organisms, as clearly demonstrated by tissues ability to decay. They continue living in a tissue or cell culture and multiply like tiny organisms. A biologist’s task is to understand how a living cell is built and performs its normal functions.

Studying the smallest living organisms’ structures became possible only after inventing microscope, i.e. after 1600. The first description and image of cells were given by English botanist Robert Hooke in 1665. Already in the early 19th century, almost all scientists began to recognize an indispensable element of plant and animal tissue structure which was called a cell.

In 1838-1839, botanist M. Schleiden and anatomist T. Schwann put forward a cell structure idea almost simultaneously. Schwann proposed the term "cell theory" and introduced this theory to a scientific community. According to the cell theory, all plants and animals consist of similar units - cells, and each cell has all the properties of a living organism. This theory has become a cornerstone of all modern biological studies.

Here are some interesting cell biology research paper topics you can explore:
