It's common after heart surgery to be sad or blue, but these feelings should pass after the first few weeks. If they don't, talk to your doctor about it. To keep your spirits up: Get dressed every day. Walk daily. Pick up your hobbies and social activities. Share your feelings with others. Get a good night's sleep. Limit visits to 15 minutes at first.
Eukaryotes. Eukaryotes are organisms made up of cells that possess a membrane-bound nucleus (that holds genetic material) as well as membrane-bound organelles. Genetic material in eukaryotes is contained within a nucleus within the cell and DNA is organized into chromosomes.
Both are small. And while most of a eukaryotic cellâs DNA is in its nucleus, mitochondria have some DNA of their own as well as ribosomes to translate its genes into proteins. Nuclear DNA is in the form of double helical strands, but mitochondrial DNA is not. Though the mitochondrial genome is much smaller than a bacterial genome, both mitochondria and prokaryotes have circular DNA.
