biology

 [bi-ol´o-je]
scientific study of living organisms. adj., adj biolog´ic, biolog´ical.
molecular biology study of molecular structures and events underlying biological processes, including relation between genes and the functional characteristics they determine.
radiation biology scientific study of the effects of ionizing radiation on living organisms.

mo·lec·u·lar bi·ol·o·gy

study of phenomena in terms of biology molecular (or chemical) interactions; traditionally, the focus of molecular biology is more specific than biochemistry in that it has an emphasis on chemical interactions involved in the replication of DNA, its "transcription" into RNA, and its "translation" into or expression in protein, that is, in the chemical reactions connecting genotype and phenotype.

molecular biology

n.
The branch of biology that deals with the structure, function, and manipulation of nucleic acids and proteins.

molecular biologist n.

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.

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.

(mŏ-lekyū-lăr bī-olŏ-jē)
Study of phenomena in terms of molecular interactions; it differs from biochemistry in that it emphasizes chemical interactions involved in the replication of DNA, its "transcription" into RNA, and its "translation" into or expression in protein.

molecular biology

The study of cellular phenomena, and especially genetics, at a molecular or chemical level. As knowledge has progressed the term has become more and more synonymous with ‘biology’, for, today, biology aims at nothing less than a full understanding of the functioning of living things in terms of the nature and interactions of their molecules.

molecular biology

the study of the structure and function of MOLECULES of biological importance, such as NUCLEIC ACIDS and PROTEINS.

(mŏ-lekyū-lăr bī-olŏ-jē)
Study of phenomena in terms of molecular interactions.

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.
