The DNA polymerase cannot start making a new DNA polymer out of nothing, it needs preexisting nucleic acid to hook the new DNA onto. What is this preexisting nucleic acid called, what enzyme makes it, and what nucleic acid is the preexisting nucleic acid made of?
When DNA is heated, it denatures; that is, the strands separate because hydrogen bonds are broken and some base-stacking and hydrophobic interactions are disrupted. The higher the temperature, the larger the number of hydrogen bonds that are broken. After reviewing DNA base pair structure, determine which of the following molecules will denature first as the temperature is raised. Explain your reasoning. a. 5′-GCATTTCGGCGCGTTA-3′ 3′-CGTAAAGCCGCGCAAT-5′ b. 5′-ATTGCGCTTATATGCT-3′ 3′-TAACGCGAATATACGA-5′
What role does bonding play in DNA? Where are hydrogen bonds located? Where are covalent bonds located? Why is that significant to the overall structure and function of DNA
