Molecular biologists focus their attention on the molecular level. When investigating genetic links to cancer, researchers need to place at the molecular biological organization level.
----------------------------------------------
When talking about biological organization levels, we are referring to the hierarchical order of the different structures that compose individuals and the systems in which they are immersed. It can go from the smallest things, such as subatomic structures, to the most complex systems, such as biomes. Among the many different biological organization levels, we can mention the molecular level.
Molecular-level refers to molecules, their interactions, and nature -organic or inorganic-. Among other disciplines, molecular biology studies this level of organization.
Molecular biology revealed several fundamental mechanisms that support the cell´s function. Polymeric biomolecules such as DNI and RNA and proteins play a unique and significant role at this level.
Molecular biology can be defined as the study of mechanisms through which molecules participate and are directly involved in genetic information transmission and cell functioning.
Molecular biology can analyze the flux of codified information that goes from DNI molecules to proteins. Cancers are the result of mutations in genetic information and all the subsequent events. So molecular biologists must focus on the molecular level to study genetic links to certain types of cancer.
