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 DNA in eukaryotes, which are wrapped around histone proteins, are called nucleosomes. The DNA in eukaryotes is linear, and nucleosomes fold through a series of successively higher order structures to eventually form a chromosome. The DNA in prokaryotes, which form a mass, are called a nucleoid. Most DNA in prokaryotes is circular, and they are supercoiled to keep them gathered together.
