The correct answer is: DNA is used as a template to make mRNA.
DNA and mRNA are both nucleic acids that play crucial roles in the process of protein synthesis. DNA contains the genetic information in the form of genes, which are segments of DNA that code for specific proteins. However, DNA is unable to directly participate in the protein synthesis process that occurs in the cell.
In order for the information stored in DNA to be used to build proteins, a process called transcription occurs. During transcription, a specific segment of DNA is copied into a molecule called mRNA. This mRNA molecule carries the genetic information from the DNA in the nucleus of the cell to the cytoplasm, where protein synthesis takes place.
The process of transcription involves the enzyme RNA polymerase, which binds to a specific region on DNA called the promoter. The RNA polymerase then moves along the DNA, unwinding it and creating a complementary RNA molecule using the base pairing rules (A with U, T with A, G with C, and C with G). This resulting RNA molecule is mRNA.
During translation, the mRNA molecule serves as a template for the production of a protein. Ribosomes read the code in the mRNA and use it to assemble a specific sequence of amino acids in the correct order to produce a protein. This process is called translation.
So, in summary, DNA is used as a template to make mRNA, which serves as the intermediary for protein synthesis. Any changes or mutations in the mRNA will not affect the DNA itself.
