The telomere is the end structure of the DNA molecule. Telomerase is the ribonuclear enzyme that helps the cell's telomere to elongate; otherwise, the telomere will shorten with each cell division through conventional DNA replication. In most mammalian species, telomerase activity is present in germ cells but not in somatic cells. Recent research shows that telomerase activity is also present in early embryos, but to our knowledge, the dynamics of this enzyme during early embryo development… CONTINUE READING
