1 Even in an adult, some cells continue to divide. Why is cell division useful even in an adult who is no longer growing? (Hint: Think about what happens when you have an injury that scrapes off some of your skin.

2. what would happen if the cell did not make a copy of dna before it divided?

Solution

1.Cell division is vital to replace dead cells and tissue renewal. This happens especially when If you get a cut or a scrape, the skin that comes back and covers.

2. If a cell didn\'t duplicate its DNA before dividing, or only partially completed its transcription (et al) processes, one of the daughter cells would be subject to almost instant death, as the DNA doesn\'t just control genetic directions, but also all directions for all integral cell life cycle processes.

Whether the cell reproduces via sexual or asexual means, this would be the case. The mechanisms for cell death are different, but the result is the same- failure of at least one daughter cell.
