BIOL 3305 Lecture Notes - Lecture 37: Metabolism, Microscope, Cytosine
Document Summary
The microscope operate the compound light microscope and the dissecting microscope to examine specimens; apply a scale to your drawings; estimate the size of microscopic objects; Cell structure describe the structures and functions of a cell; Functions of the cell: cell metabolism and energy use: the chemical reactions that occur within cells. B explain surface area to volume ratios in relation to cells; B explain the evidence that dna encodes genetic information; The sequence of organic bases in dna stores genetic information. The sides of the ladder are formed by covalent bonds between the sugar molecules and phosphate groups of adjacent nucleotides. Base pairs: adenine- thymine (only have 2 hydrogen bonds) while guanine-cytosine (have 3 hydrogen bonds) B describe the structure of dna and how it replicates; Two strands of nucleotides joined together to create double helix structure. Nucleotide consists of a sugar (monosaccharide), nitrogenous organic base and a phosphate group.
