Document Summary
Straight line > 2e- shared in a covalent bond. In nature, always find d form of sugars. L form keeps the aldehyde group the same, but mirrored so hydroxyl groups are on opposite sides. Like right hand doesn"t fit in a left hand glove. Draw the general structure of a nucleotide and or a purine and pyrimidine base. Central dogma: information flows in a sequential manner from nucleic acids to proteins. Dna stores genetic information over generations from cell to cell and organism to organism. *replication* mrna information stored over short term if it will be expressed as a protein. C has an amino group that is reactive and turns it into a carbonyl group. Have different functional groups, which affects their ability to make hydrogen bonds. Because of close proximity of negative charges trying to repel. Dropping a phosphate group leads to an excess of energy.
