The estimated due date (EDD or EDC) is the date that spontaneous onset of labor is expected to occur. The due date may be estimated by adding 280 days (9 months and 7 days) to the first day of the last menstrual period (LMP). This is the method used by pregnancy wheels.
A cell nucleus (plural: cell nuclei) is the part of the cell which contains the genetic code, the DNA. The nucleus is small and round, and it works as the cell's control center. It contains chromosomes which house the DNA. The human body contains billions of cells, most of which have a nucleus. All eukaryote organisms have nuclei in their cells, even the many eukaryotes that are single-celled.
The word nucleus is derived from a Latin word nucleus or nuculeus which means 'kernel'. Nucleus a double-membrane bound cell organelle present in eukaryotic cells. The nucleus constitutes most of the genetic material of the cell-the DNA.The nucleus maintains the integrity of the genes which regulate the gene expression, in-turn regulating the activities of the cell.lant cell nucleus is a double-membrane bound organelle. It controls the activities of the cell and is known as the master mind or the control center of the cell. The plant cell wall has two layers-the outer membrane and the inner membrane, which encloses a tiny space known as perinuclear space.
