Answer from: val6298

DNA replication requires a very high energy. It has to be fast and accurate as well. Therefore instead of opening in one go, long DNA molecules of eukaryotes have a large number of replicons all of which work simultaneously.

Explanation:

While replicating, the entria DNA molecule to keep the whole molecule stabilised does not open in one go because it would be highly expens energetically. ... Actually , unwinding creates tension in the molecule us cucoiled parts start forming super coils due to the interaction of exposed nucleotides

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
