I'm Gary Buckholz, Palliative Medicine Fellowship Director at The Institute for Palliative Medicine at San Diego Hospice. One of the most important things I can do is to decrease the symptom burden for patients who are suffering, and one of the most common symptoms I treat is shortness of breath, or dyspnea.
Organelles are specialized membrane-enclosed structures in the cytoplasm of eukaryotic cells. The nucleus, which contains DNA in the form of chromosomes, is the most characteristic eukaryotic organelle.The nuclear envelope is connected to a system of membranes in the; cytoplasm called the endoplasmic reticulum (ER).he nucleus, which contains DNA in the form of chromosomes, is the most characteristic eukaryotic organelle.

No, really. In eukaryotic cells, the first stage of this process takes place in the nucleus and consists of specific portions of the DNA, called genes, being copied, or transcribed, into small strands of ribonucleic acid, or RNA. RNA containing a copy, or transcript, of DNA is called messenger RNA, or mRNA. cell is defined as eukaryotic if it has a membrane-bound nucleus. Any organism composed of eukaryotic cells is also considered a eukaryotic organism. Case in point: You. Biologists do not know of any single organism on Earth that is composed of both eukaryotic and prokaryotic cells.
