I believe using gel electrophoresis to separate and identify plasmids and short linear pieces of DNA would be important if one is making a recombinant plasmid and has to verify that he/she has been successful. Gel electrophoresis is a technique that is used to separate mixtures of DNA, RNA, or proteins according to molecular size. The molecules being separated are pushed by an electrical field through a gel that contains small pores.
Grain roundness goes to grain size , sediment sorting goes to loss of edges ,layering goes to stratification of sediments and rocks , texture range of particle size . hope this right!
The scientific method involves developing a question to answer a hypothesis. It has to determine whether a hypothesis is true or not which would involve questions that can be answered through testing and observation of the subject.
