Why is it more important to check for errors during dna replication than during translation?

I think the answer would be because if there is an error in the DNA replication, it would affect one generation of cells. if the error would fall in the transcription or translation, there would only be one cell affected.

When the ball is rising up, it gains kinetic energy. when the ball reaches the very top, it will have all potential energy, until it falls back down and gains it kinetic energy. finally when you catch the ball or it falls back down, it would have gained its potential energy back.
