DNA and mRNA are related through the process of transcription. DNA, which is found in the cell nucleus, is used as a template to create mRNA molecules through a process called transcription. During transcription, an enzyme called RNA polymerase synthesizes mRNA using the DNA template. The mRNA molecule is a complementary copy of the DNA sequence.
Therefore, the statement "DNA is used as a template to make mRNA" is accurate. The sequence of the DNA is transcribed into the mRNA, which carries the genetic instructions to the cytoplasm, where it is translated into proteins.
However, the statement "If there has been a mutation in mRNA, the DNA will not change" is incorrect. Mutations can occur in both DNA and mRNA. Mutations in DNA can happen due to errors during DNA replication or external factors like radiation or chemicals. These mutations can be inherited or can occur during an individual's lifetime. Mutations in mRNA can occur during the transcription process or as a result of errors during RNA processing.
It is important to note that DNA mutations are usually permanent and can be passed on to future generations, while mRNA mutations are usually temporary and do not affect the genetic code of an individual's offspring.
