It is in the latter conceptual terms that chemistry interprets biological phenomena. An essential link between the two disciplines is provided by information about the molecular structure of the relevant biological system.
Today, as structural knowledge of complex biological systems progresses, the associated biological processes enter the domain of chemical interpretation and analysis. A recent example is from the extensive and elegant structural studies of the RNA polymerase transcription machinery carried out by Roger D.

From the Nobel lecture of Professor Roger Kornberg. The elucidation of the sequence of three billion nucleo-base pairs of the human DNA and the sequencing of human chromosomes—as an outcome of the Human Genome project—constitutes a historical milestone. In the years to come, the analysis of genomic data, that has become available, will continue to bear fruit in many expected ways and in some yet unpredicted areas.
As could be anticipated, the enhanced interaction between biology and chemistry has had an immediate impact in the area of healthcare and medicine. Expanding knowledge about the function of protein kinases—in intracellular signal transduction and regulation of critical cellular processes—coupled with structural data, has served as a matrix for the design of clinically useful drugs.
An impressive example is the development of the drug for the treatment of the haematological stem-cell disorder chronic myeloid leukemia CML.
This disorder involves translocations between chromosone 22 and chromosone 9, resulting in the abnormal BCR-ABL [breakpoint cluster region—Abelson] oncogene which codes for the tyrosine kinase responsible for CML. Treatment of CML has been sought in the development of specific tyrosine kinase inhibitors.
Application of combinatorial chemistry coupled with high through-put screening has led to the development of several clinically useful drugs e. A multitargeted kinase inhibitor named Sorafenib is currently being used for the treatment of kidney cancer that is resistant to interferon-alpha or interleukin Sorafenib is also being studied for the potential treatment of other cancers, including melanoma, lung cancer, and mesothelioma.
In line with its mission, IUPAC advocates the creation of strong links with other disciplines so that chemistry can play a vital role in the development of multidisciplinary perspectives. In the preceding decades, the fields of medicine and agriculture have benefitted from increased interdisciplinary interaction and coordination between chemistry and biology.

As far as how that relates to your education, if you major in biology, you will be learning a lot of chemistry, and if you major in chemistry, you will be learning a fair bit of biology as well.
In terms of difficulty, the choice is subjective, but at the upper levels, they may be comparably matched. There are also crossover topics and sometimes majors such as chemical biology and biochemistry which are more different than they sound. Both however exist at an intersection between the two.
So you should take some time to learn about these more specialized majors too. Rather you should base your decision on what kind of career you are interested in after college. Biologists and chemists go on to very different futures, and it is important to remember that college is just a few years. Integrated science classes increasingly linking the subjects of biology, chemistry and physics.
What Is The Difference Between Biology And Chemistry? - Career Igniter
Defining and Integrating Science Disciplines As Merriam-Webster defines them, biology is the study of life, more specifically "a branch of knowledge that deals with living organisms and vital processes"; chemistry consists of "a science that deals with the composition, structure and properties of substances and with the transformations that they undergo"; and physics means "a science that deals with matter and energy and their interactions.
All life depends on chemical processes. The chemical process of photosynthesis, which uses the sun's energy to convert water and carbon dioxide into glucose sugarforms the base of most food chains. Like photosynthesis, chemosynthesis stores energy through chemical processes and underpins the food chains along deep sea vents, suggesting possibilities for Earth's earliest life and life on other planets and moons. Sciencing Video Vault Bioluminescence means living light.
Chemical processes in a variety of organisms, ranging from plants to fungi to animals, including dinoflagellates, jellyfish and angler fish, create this living light.
Digestion and cellular respiration also depend on chemical reactions within living organisms. Understanding the chemistry of oil production, based on the decomposition of algae under heat and pressure, offers one solution to the global energy crisis by making petroleum from algae, but it potentially creates another environmental crisis through continued use of previously nonrenewable fossil fuels.
