BIOC 302 Lecture Notes - Lecture 19: Dimethyl Sulfoxide, London Dispersion Force, Hydrogen Bond
Document Summary
To make a dinucleoide the phosphate is esteriied to the 3"-oh of another nucleoide. Direcionality 5" to 3" whenever we sequence we start 5" to 3". Dna is normally found in as a double helix. Two polynucleoides associated by hydrogen bonding between bases. The interacions are speciic: if you mix g and c together a exothermic reacion. Heat is release: this also occurs with a and t but a litle less energy is formed because they form 1 less hydrogen bond the occurs. Bioc part 2. 2: other combinaions show no change in heat. This is because in g-c complex the 3 complementary h bonds can form: donors and acceptors. There is always the same spacing between pairs. Also there is almost idenical distance between c1"s then gives that structure no mater what the sequence. The sequence of one determines the sequence of the other. The 2 strands are ani-parallel they run in opposite direcions7 which is.
