Biology
Biology is the natural science that involves the study of life and living organisms, including their physical structure, chemical composition, function, development and evolution. Modern biology is a vast field, composed of many branches. Despite the broad scope and the complexity of the science, there are certain unifying concepts that consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the creation of new species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy to maintain a stable and vital condition defined as homeostasis. See glossary of biology.
Genetics
Genetics is the study of genes, genetic variation, and heredity in living organisms. It is generally considered a field of biology, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.
Molecular Biology
Molecular biology is a branch of biochemistry which concerns the molecular basis of biological activity between biomolecules in the various systems of a cell, including the interactions between DNA, RNA, and proteins and their biosynthesis, as well as the regulation of these interactions. Writing in Nature in 1961, William Astbury described molecular biology as:

Despite the beliefs and teachings of religion and psychology, impulses are biological and psychic directional signals to nudge the individual toward his or her greatest opportunities for expression and development privately, and also to insure the person's contribution to mass social reality.

Genetics
Naomi: Each person is born with their fate written into their own genetic code... it's unchangeable, immutable... But that's not all there is to life. I finally realized that. I told you before. The reason that I was interested in genes and DNA. Because I wanted to know who I was... where I came from. I thought that if I analyzed my DNA I could find out who I was, who my parents were. And I thought that if I knew that, then I'd know what path I should take in life. But I was wrong. I didn't find anything. I didn't learn anything. Just like with the Genome Soldiers... you can input all the genetic information, but that doesn't make them into the strongest soldiers. The most we can say about DNA is that it governs a person's potential strengths... potential destiny. You mustn't allow yourself to be chained to fate... to be ruled by your genes. Humans can choose the type of life they want to live.

Biology
Any competent biologist is aware of a multitude of problems yet unresolved and of questions yet unanswered. After all, biologic research shows no sign of approaching completion; quite the opposite is true. Disagreements and clashes of opinion are rife among biologists, as they should be in a living and growing science. Antievolutionists mistake, or pretend to mistake, these disagreements as indications of dubiousness of the entire doctrine of evolution. Their favorite sport is stringing together quotations, carefully and sometimes expertly taken out of context, to show that nothing is really established or agreed upon among evolutionists. Some of my colleagues and myself have been amused and amazed to read ourselves quoted in a way showing that we are really antievolutionists under the skin.
