DNA and mRNA are related in the sense that DNA serves as the template to make mRNA. This process is known as transcription, where the DNA sequence is transcribed into an RNA sequence, specifically mRNA. The mRNA molecule then carries the genetic information from the DNA to the ribosomes, where it is used as a template for protein synthesis (translation). Mutations can occur in both DNA and mRNA, but a mutation in mRNA does not change the DNA sequence, and a mutation in DNA does not directly change the mRNA sequence.
DNA and mRNA are related in the process of gene expression. DNA, or deoxyribonucleic acid, contains the genetic instructions for building and maintaining an organism. It is made up of a sequence of nucleotide bases: adenine (A), thymine (T), cytosine (C), and guanine (G).
During gene expression, the information in the DNA is copied onto a molecule called mRNA, or messenger RNA. This process is known as transcription, and it takes place in the nucleus of the cell. The DNA molecule unwinds, and an enzyme called RNA polymerase attaches to one of the DNA strands and starts adding complementary RNA nucleotides. Unlike DNA, mRNA contains the base uracil (U) instead of thymine (T). So, where the DNA strand has an A, the mRNA will have a U.
The mRNA molecule is formed by following the template of the DNA sequence. Once the mRNA is transcribed, it is processed and leaves the nucleus, carrying the genetic information to the ribosomes in the cytoplasm. The ribosomes read the sequence of the mRNA to synthesize proteins in a process called translation.
Overall, DNA is used as a template to make mRNA, and mRNA is used as a template for protein synthesis. However, it is important to note that mutations can occur in both DNA and mRNA. In the case of a mutation in DNA, it can be inherited or arise spontaneously and may lead to changes in the resulting mRNA and protein. On the other hand, if there is a mutation in the mRNA, it does not affect the underlying DNA sequence.
So, the correct answer is: DNA is used as a template to make mRNA.
