How can i remember the definition of rflps? read below for the definition. i need memorizing it. the dna segments of varying lengths produced when a restriction enzyme cuts different samples of dna at its restriction site

RFLP stands for restriction fragment length polymorphism.

The restriction fragments are fragments formed after getting restricted (cut by restriction enzymes).

Polymorphism means many (poly) forms (morphism). So, length polymorphism means many lengths.

So, RFLP means the cut DNA (restriction fragments) have many lengths (length polymorphism).

If you know what RFLP stands for, you can easily remember the full definition.

The answer is c i just finished taking the test

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.
