Document Summary

Structure discovered by watson and crick in 1953. Rungs - bases (a, g, c, t) Nucleotides are the building blocks for life. Phosphate -> sugar -> nitrogen base(a, t, g, c) Are used to recreate molecule during replication. A only bonds with t: 2 hydrogen bonds. C only bonds with g: 3 hydrogen bonds. Enzymes unwinds and break apart double helix. Nuw bases join via rules of complementarity (a-t) (c-g) Results in 2 double-stranded dna molecules exactly like the. Combine differently to produce millions of proteins. Proteins differ in number and sequence of amino acids. Amino acids are coded by blocks of 3 nucleotides. Unzipping dna to make a template for rna. Only copying over a specific amount of information for a specific trait/gene. Enzymes unzip dna at a specific point for a specific trait. Rna nucleotides attach to complementary bases on dna molecule (u replaces t in rna) Brings in free-floating rna nucleotides to create the.
