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.

DNA is the genetic material of a cell. The DNA contains the genetic code or instructions for how to make proteins. Eukaryotic cells have a nucleus, which is like the control center for the cell. It is in this organelle that DNA resides. However, prokaryotic cells do not have a nucleus. Instead, the DNA exists in a coiled loop floating around in the cytoplasm in the nucleoid region. Ribosomes Ribosomes are small organelles that float in the cytoplasm or are attached to other structures.
