Research paper writing


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

Molecular biology topics

molecular biology topics

Molecular biology is a field of biology that studies all the activities and systems at the molecular level. It is a new branch closely related to long-established research fields such as biochemistry, biophysics, and bioorganic chemistry. Below, you can find the list of some interesting biology topics on this subject:

  • The main molecular biology development stages
  • Tasks and methods of molecular biology
  • Unique and repetitive genes
  • DNA double helix polymorphism
  • Genome mapping
  • Genetic recombination types
  • Non-nuclear eukaryotic genomes

Cell biology topics

In a multicellular organism, all complex activities are a result of the constituent cells coordinated activity. A biologist’s task is to understand how a living cell is built and how it performs its functions.

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

In 1838-1839, a botanist M. Schleiden and anatomist T. Schwann put forward a cell structure idea almost simultaneously. Schwann proposed the term “cell theory” and introduced it to a scientific community. According to the cell theory, all plants and animals consist of similar units called 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:

  • Recent advances in cell biology
