molecular biology  study of molecular structures and events underlying biological processes, including relationships between genes and the functional characteristics they determine.
radiation biology  scientific study of effects of ionizing radiation on living organisms.

molecular biology
n.
The branch of biology that deals with the formation, structure, and activity of macromolecules essential to life, such as nucleic acids, and especially with their role in cell replication and the transmission of genetic information.

molecular biology
[məlek′yələr]
Etymology: L, molecula, small mass; Gk, bios, life, logos, science
the branch of biology that deals with the physical and chemical interactions of molecules involved in life functions.

biology [bi-ol´o-je]
scientific study of living organisms. adj., adj biolog´ic, biolog´ical.

molecular biology,
n the study of biology from the viewpoint of the physical and chemical interactions of molecules involved in life functions.

molecular
of, pertaining to, or composed of molecules.

molecular activity
see enzyme activity.
molecular biology
study of the biochemical and biophysical aspects of the structure and function of genes and other subcellular entities, and of such specific proteins as hemoglobins, enzymes and hormones; it provides knowledge of cellular differentiation and metabolism and of comparative evolution.
molecular layer
layers of cells in both cerebellar and cerebral cortices.
molecular mimicry
see antigenic mimicry.
molecular weight
see molecular weight.

molecular biology
A major discipline that marked its birth with Watson and Crick's seminal report, 'General Implications of the Structure of Deoxyribonucleic Acid', which elucidated the double helical nature of DNA; MB seeks to understand the mechanisms controlling gene expression, in physiologic and disease states, and provide the tools necessary for treating genetic diseases. See DNA, Human Genome Project.
