The correct answer is: DNA is used as a template to make mRNA.
To understand how DNA and mRNA are related, we need to understand the central dogma of molecular biology. The central dogma states that genetic information flows from DNA to RNA to protein.
DNA (deoxyribonucleic acid) is the genetic material that contains the instructions for building and maintaining an organism. It consists of a double-stranded helix structure made up of four nucleotide bases: adenine (A), thymine (T), cytosine (C), and guanine (G).
mRNA (messenger RNA) is a single-stranded molecule that carries the genetic information from DNA to the protein synthesis machinery of a cell. mRNA is synthesized through a process called transcription, where an enzyme called RNA polymerase uses one strand of the DNA molecule as a template to construct a complementary RNA sequence. This process occurs in the nucleus of eukaryotic cells and the cytoplasm of prokaryotic cells.
Therefore, DNA serves as a template for the synthesis of mRNA. The sequence of bases in DNA is transcribed onto mRNA, with the complementary base pairing rules followed (A with U, T with A, C with G, and G with C). This mRNA molecule carries the genetic information from the DNA to the ribosomes, where it is translated into a specific amino acid sequence to build proteins.
It is important to note that mutations can occur in both DNA and mRNA. A mutation is a change in the nucleotide sequence of the genetic material. If there is a mutation in the DNA, it can lead to a change in the corresponding mRNA sequence. However, if there is a mutation in the mRNA, it does not change the DNA sequence.
In summary, DNA and mRNA are related in that DNA serves as a template to make mRNA through the process of transcription. Mutations can occur in both DNA and mRNA, but a mutation in the DNA sequence will affect the corresponding mRNA sequence.
If there has been a mutation in mRNA, the DNA will not change.
