Fuel costs affect delivery of materials to sometimes. remote sites. Heavy equipment costs (steel, fuel, tires) are a. higher proportion of trail and highway costs than.
DNA Replication is Semiconservative When the replication process is complete, two DNA molecules â identical to each other and identical to the original â have been produced. Each strand of the original molecule has remained intact as it served as the template for the synthesis of a complementary strand.
Specific base pairing makes DNA replication possible. Because of  how the bases pair up (A-T, G-C) the 2 strands come together like a  molecule 'zipper'.    The 2 str â¦ ands of DNA unwinds and is copied following the base pair  rule.
