Document Summary
Capable of coding for and transmitting biological information. Polymers for storage, transmission, & use of genetic info. Rna: intermediates that take info. from dna & use it to specify amino acid sequences of proteins & control synthesis of other rna. Dna rna protein: carries out many of life"s functions. 2 strands of double helix can serve as a template for a new strand of dna. 13. 3. 2: an elegant experiment demonstrated that dna replication is semiconservative. Oh) group on the 3" carbon two phosphates on incoming dntp are removed & the remaining phosphate bonds: energy is released by hydrolysis of dntp & energy drives condensation reaction. 13. 3. 5: many other proteins assist with dna polymerization. 13. 3. 6: the two dna strands grow differently at the replication fork: replication fork opens up like a zipper, leading strand & lagging strand: must be synthesized as new nucleotides new stretches of dna are called.
