Gene Expression


Gene expression

  • the phenotypic manifestation of a gene or genes by the processes of genetic transcription and genetic translation.

Gene expression analysis

  • the determination of the pattern of genes expressed at the level of genetic transcription, under specific circumstances or in a specific cell.

How It Works

gene expression

When genes are expressed, the genetic information (base sequence) on DNA is first copied to a molecule of mRNA (transcription). The mRNA molecules then leave the cell nucleus and enter the cytoplasm, where they participate in protein synthesis by specifying the particular amino acids that make up individual proteins (translation).
