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.
Prokaryotic DNA can be found in a coiled loop floating in the cytoplasm in a region called the nucleoid (meaning nucleus-like). In other words, the nucleoid is the area in a prokaryotic cell where DNA is located.Prokaryotes compress their DNA into a small space through a process called supercoiling. Supercoiling DNA allows it to be packaged efficiently into the small cell.danimai | (Level 1) Honors.n other words, the nucleoid is the area in a prokaryotic cell where DNA is located.
