Document Summary
Explain the evidence that supports the identity of dna as hereditary material. Describe the process of dna replication and predict complementary dna sequences. Dna molecules are comprised of thousands of nucleotides joined together in a chain by their phosphate groups. > in each species, the amount of a is equal to t, and amount of c is equal to g. Used this technique to discover the physical shape of dna. This was the rst indication that dna was composed of a ___________ __________ structure. Watson & crick"s model of dna (double helix) Dna replication: hydrogen bonds between bases broken. Each single strand has the information to make a new complementary strand: t in the original strand, an _________ will be placed opposite it in the new strand. Many enzymes and cofactors are required: _________ enzymes break the hydrogen bonds between bases, dna polymerases synthesize the new strand recognizing each base and attaching the correct complementary base.
