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 double stranded, so 2. RNA is single stranded, so 1. DNA is located in the nucleus. RNA is located in a few places because there are different types of RNA....RNA is copied in the nucleus (mRNA), and then shipped out to a ribosome (which has rRNA and tRNA), floating in the cytoplasm. DNA has 2 strands, RNA just 1, and they both can be found in the nucleus of the cell.
