Inside the membrane, the cytoplasm takes up most of the cell's volume. All cells (except red blood cells which lack a cell nucleus and most organelles to accommodate maximum space for hemoglobin) possess DNA, the hereditary material of genes, and RNA, containing the information necessary to build various proteins such as enzymes, the cell's primary machinery.
Doula. A doula, is a nonmedical person who assists a woman before, during, or after childbirth, as well as her partner and/or family by providing information, physical assistance, and emotional support.
