Medicines are given to stop the heart; a heart-lung bypass machine keeps blood and oxygen moving throughout the body during surgery. This allows the surgeon to operate on a still heart. After surgery, blood flow to the heart is restored. Usually, the heart starts beating again on its own. Sometimes mild electric shocks are used to restart the heart.
Answer     It is located all throughout the cytoplasm. Prokaryotic cells do not have a nucleus so the DNA is located in the cytoplasm. The DNA in prokaryotic cells is a â¦ lso usually found in a circular ring that is coiled up into figure eights called supercoils.
DNA is located in the nucleoid of the cell and is not associated with protein A plasmid is an extra-chromosomal DNA molecule separate from the chromosomal DNA which is capable of replicating independently of the chromosomal DNA. Plasmids usually occur naturally in bacteria.A chromosome is an organized structure of DNA and protein that is found in cells. A chromosome is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences.Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions. 1. Plasmids are circular and double stranded. 2. chromosome is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences.
