Biochemistry
Biochemistry is the study of the chemical substances and vital
processes
occurring in living organisms. It focuses on the role, function and
structure of biomolecules.
Biochemistry often overlaps with molecular biology and genetics.
Molecular biology and genetics
Molecular biology concentrates on the study of the structure,
behaviour and interaction of individual molecules and the way
organisms reproduce at cellular level.
The discipline also studies other important elements such as the
nucleic
acids which provide the basis for cellular reproduction.
Molecular biology also deals with the concept of replication,
transcription and translation.
Genetics is the science of genes, heredity and variation in living
organisms.
