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.
Eukaryotic DNA All the animals, plants, and fungus are eukaryotic organisms; nuclear envelope is the most defining character for all eukaryotic organisms. In eukaryotes, mostly DNA is stored inside the cell nucleus, but some are found within the organelles such as chloroplasts and mitochondria. Histone protein and organized DNA are compacted inside the chromosome.
