How are DNA and mRNA related?

mRNA is used as a template to make DNA
If there has been a mutation an mRNA, the DNA will not change

DNA and mRNA are related in that DNA is used as a template to make mRNA. This process is known as transcription. The information encoded in the DNA is transcribed into mRNA, which then carries the genetic information from the DNA to the ribosomes in the cell, where proteins are synthesized. If there is a mutation in the DNA, this can lead to changes in the mRNA as well, potentially affecting the proteins that are produced.
