Your answer is correct. Chitin provide the strength to insect exoskeletons. Cellulose is the strength for plant. Starch and glycogen are energy sources for life.
Smaller DNA fragments migrate <u>more quickly</u> and further over a given period of time than larger fragments.
<h3>Gel electrophoresis and DNA fragments</h3>
Gel electrophoresis is a method to separate DNA fragments (or RNA and other macromolecules) based on their size and charge, involving a gel called agarose. The molecules will travel through the gel at different speeds or in different directions, which allows them to be separated from each other.
Because all DNA molecules have the same amount of charge per mass, gel electrophoresis of DNA fragments separates DNA molecules based on size only. Shorter pieces of DNA travel through the pores of the gel more quickly than longer ones do.

Answer:
When water or any other liquid is poured into the communicating tubes shown in Fig. 10.9 it stands at the same level in each tube. This illustrates the popular saying that, “water finds its own level
1.) DNA replication is a process where the double helix is unwound and each strand is replicated to create another. This occurs in all replication of the body cells, or reproductive cells, a common process called mitosis.
2) The original DNA molecule is exactly the same as the replicated molecule, but the original is called the parent cell and the replicated molecule the daughter cell.
3) Enzymes act as catalysts/proofreaders of DNA replication. For example, Primase synthesizes RNA primer, or DNA ligase joins DNA strands together.
