Background: DNA nucleotides (i.e A, T, G, and C) are naturally found in a paired, or bonded, arrangement (i.e. the double helix) within the nucleus of every cell. This structure makes the process of replication that occurs prior to mitosis and meiosis very reliable. The purpose of DNA, though, is not simply to make copies of itself, but to provide a set of instructions for the synthesis or "construction" of biomolecules, such as proteins. Why is transcription (i.e. the formation of an RNA copy of a given gene) a necessary step in the "construction" process highlighted above? What is the cell looking to ultimately do with this RNA information?

How does DNA replication occur in a precise manner to ensure that identical genetic information is put into the new chromatid? See Figures 8.12 and 8.13. FIGURE 8.12 In DNA replication, the two polynucleotide strands uncoil, and each is a template for synthesizing a new strand. A replicated DNA molecule contains one new strand and one old strand. This mechanism is called semiconservative replication. FIGURE 8.13 A close-up look at the process of DNA replication. (a) As the strands uncoil, bases are added to the newly synthesized strand by complementary base pairing with bases in the template strand. The new bases are linked together by DNA polymerase. (b) DNA synthesis can proceed only in the 5 3 direction; newly synthesized DNA on one template strand is made in short segments and linked together by the enzyme DNA ligase.
