difference between genome and gene
â¢ Gene is a segment or a portion of DNA molecule while genome is the total DNA content in a cell. â¢ Genes code for proteins. Genome itself cannot code for proteins as it contains almost all the DNA. Since the gene is only a portion of a DNA molecule, that part is enough to code for proteins.
The genome is the set of all genes, regulatory sequences, and noncoding information within an organism's DNA. Thus, the study of genomics considers all of the genetic material contained within and shared between organisms.
