I always find books talking about molecular biology and molecular genetics as one. Is there a difference between them or are they synonyms for each other? and if there is a difference between them, what is the difference?
Oxford defines 'genetics' as 'the study of heredity and the variation of inherited characteristics.' Molecular genetics is the study of genetics at the molecular level. It includes topics like how DNA is copied and repaired, sequencing genes and genomes, determining how specific genetic variants cause different phenotypes in terms of the DNA sequence change and its molecular consequences, and many more.
Molecular genetics is a subset of molecular biology, which is much broader - it's the study of life at the molecular level, and it's not confined to heredity or the relationship between genes and phenotypes. Molecular biology includes stuff like understanding how photosynthesis produces sugar molecules, how viruses get inside cells, why cyanide is toxic, etc.
Hello Khaled G. Khalifa
There is a very small difference between Molecular Biology and Molecular Genetics.
In Molecular Biology, it's more about the interactions between molecules that is considered. The nature of biological phenomena at the molecular level through the study of DNA and RNA, proteins, and other macromolecules involved in genetic information and cell function, characteristically making use of advanced tools and techniques of separation, manipulation, imaging, and analysis.
On the other hand, Molecular Genetics is Molecular Biology. In Molecular Genetics, one is interested in the function and action of genes. It is basically the study of genes and the ways in which their RNA and protein products work together to make cells and organisms. By understanding genetic function at a molecular level, one can learn how normal organisms develop and function, and how genetic changes lead to disease.
Best.
molecular genetics uses techniques from molecular biology, just adapted to genetics for higher number of samples to make some statistics.

Molecular biology and molecular genetics are two closely related fields that often overlap and are sometimes used interchangeably. However, they do have some distinct differences.
Molecular biology is a broad field that focuses on the study of biological processes at the molecular level. This includes the structure, function, and regulation of molecules such as DNA, RNA, and proteins. Molecular biologists often use techniques like molecular cloning, gene expression analysis, and protein purification to study these molecules and their roles in biological processes.
Molecular genetics, on the other hand, is a subfield of molecular biology that specifically focuses on the study of genetics at the molecular level. This includes the structure, function, and regulation of genetic material (DNA and RNA) and how it is passed from one generation to the next. Molecular geneticists often use techniques like DNA sequencing, genetic engineering, and gene mapping to study genetics at the molecular level.
In summary, molecular biology is a broad field that encompasses the study of biological processes at the molecular level, while molecular genetics is a subfield that specifically focuses on the study of genetics at the molecular level. Both fields involve the use of techniques like DNA sequencing and gene expression analysis, but molecular genetics often has a more specific focus on the structure, function, and regulation of genetic material.
