Q. Is a gene the same as a DNA molecule?
Genes are units of heredity. A gene is a section or segment of a DNA molecule. This section of DNA provides a genetic code for synthesis of proteins. Nucleicacid language of the gene is written as a sequence of bases on DNA molecule. Such a sequence may read G- C- T- T- A- C- C- G- A- T- T. . . . This is the molecular 'language' that will eventually specify an amino acid sequence in a protein.
