Explain how DNA synthesis is carried out.

Information about the composition of the protein is taken from the DNA of the cell. Messenger RNA reads information from DNA and transfers it to the ribosome. And there protein is already synthesized. Protein synthesis occurs in the ribosomes of the cell.
The DNA molecule, consisting of two helices, doubles as the cell divides. Doubling DNA is based on the fact that when the strands are twisted, a complementary copy can be added to each strand, thus obtaining two strands of the DNA molecule that copy the original.
