Protein Synthesis Paper
What is DNA? DNA is a nucleic acid that carries the genetic information in cells and some viruses, consisting of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA sequences are replicated by the cell prior to cell division and may include genes, intergenic spacers, and regions that bind to regulatory proteins.
What is RNA ? A nucleic acid present in all living cells and many viruses, consisting of a long, usually single-stranded chain of alternating phosphate and ribose units, with one of the bases adenine, guanine, cytosine, or uracil bonded to each ribose molecule. RNA molecules are involved in protein synthesis and sometimes in the transmission of genetic information. Also called ribonucleic acid.

Gyrase cuts the double-stranded DNA to prepare it, next, the enzyme helicase unzips the DNA. At this point, single-strand binding proteins keep the two halves of the double helix separated, during which time the enzyme polymerase pair nucleotides together. This process creates two double helices from one. While pairing nucleotides together, polymerase simultaneously proofreads the process to make sure that the pairing is correct. DNA replication is important because it creates a second copy of DNA that must go into one of the two daughter cells when a cell divides. Without replication, each cell lacks enough genetic material to provide instructions for creating proteins essential for bodily
