This mRNA travels out of the nucleus into the cytoplasm to inform protein (and other molecule) synthesis. DNA itself is a macromolecule that's made up of two complementary strands that are each made up of individual subunits called nucleotides.It's these bonds that form between the complementary base sequence of the nitrogenous bases that hold together the two DNA strands to form the double-helical structure that makes DNA famous. In mRNA, three consecutive nucleotides encode either a stop signal for protein synthesis or an amino acid. The DNA contains the master plan for the creation of the proteins and other molecules and systems of the cell, but the carrying out of the plan involves transfer of the relevant information to RNA in a process called transcription. It runs in the five prime (5’) to three prime (3’) direction. In the mRNA, Uracil is substituted for thymine as the base complementary to adenine. The other strand is called the non-template strand. The other strand is called the non-template strand. It also typically has segments called introns that are not translated as well as segments called exons that are actually part of the pattern for the protein. Sense strand runs from 5’ to 3’ direction, containing the same base pair sequence to the transcribing mRNA. In mRNA, three consecutive nucleotides encode either a stop signal for protein synthesis or an amino acid. A coding region of the DNA for a specific protein (a gene) contains the pattern for the creation of the protein. In a real cell, the RNA molecule would be anywhere from 100 to 10,000 bases long.
