Eggs follow a very different developmental path from sperm. Once a male hits puberty, sperm cells are produced continuously throughout his life. Eggs, however, are all produced during the fetal stage.
Once formed, eggs enter a long dormant state called the dictyate stage, in which the process of cell division (meiosis) is paused partway through. This dormant period ends only when the egg is ovulated.

A protein that regulates mRNA decoding can itself be regulated with implications for understanding cancer
Decoding of messenger RNA (mRNA) occurs during translation, the vital cellular process that builds proteins. Errors in this process are known to lead to cancer growth. Scientists at St. Jude Children's Research Hospital identified how one factor involved in mRNA decoding can be a
