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.

The distinction is that eukaryotic cells have a true nucleus containing their DNA, whereas prokaryotic cells do not have a nucleus. Both eukaryotes and prokaryotes contain large RNA / protein structures called ribosomes, which produce protein.nother difference is that ribosomes in prokaryotes are smaller than in eukaryotes. However, two organelles found in many eukaryotic cells, mitochondria and chloroplasts, contain ribosomes similar in size and makeup to those found in prokaryotes.
