Molecular Biology: Relationship with Biochemistry and Genetics

Molecular biology is a discipline of biology and it deals with the molecular basis of biological activity. This stem interconnects other areas of biology and chemistry, mainly genetics  and biochemistry. Molecular biology largely concerns itself with understanding the interactions between the various systems of a cell, including the interactions between the different types of macromolecules e.g., DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

Universe and Life Arising

About fifteen to twenty billion years ago, the universe arose as a cataclysmic eruption of hot, energy-rich subatomic particles.The simplest elements (hydrogen and helium) were formed shortly. In the early stage, the universe was very hot. As it expanded and cooled, material condensed under the influence of gravity to form stars. Some stars became enormous and then exploded as supernovae.

Biochemistry

Take a close look at the living organisms. Actually, they are the collection of thousands of different lifeless biomolecules. Biochemistry asks how the amazing properties of living organisms arise  from these different lifeless biomolecules. When these molecules are isolated and examined individually, they follow all the physical and chemical laws that describe the behavior of lifeless matter. Notably all the processes occurring in living organisms follow these laws. The study of biochemistry give you an idea about how the collections of inanimate molecules that constitute living organisms interact to maintain and continue life animated solely by these laws (physical and chemical laws) that govern the nonliving universe.
