The daughter cells from mitosis are called diploid cells. Diploid cells have two complete sets of chromosomes. Since the daughter cells have exact copies of their parent cell's DNA, no genetic diversity is created through mitosis in normal healthy cells.
Expressed gene. Expressed gene gene Expression. (Science: molecular biology) The full use of the information in a gene via transcription and translation leading to production of a protein and hence the appearance of the phenotype determined by that gene.xpressed gene.

Promoters are the sequences of DNA that determine when a gene is expressed. These sections of DNA sit in front of genes and provide a âlanding siteâ for transcription factors (proteins that switch gene expression on and off) and RNA polymerase (the protein that reads DNA and makes an mRNA copy).ll organisms make proteins in essentially the same way. The process starts with a gene â the âinstruction manualâ for constructing the protein. For this reason, the process of making a protein is also called gene expression. Gene expression has two main stages: transcription and translation.
