What contribution does DNA make in the formation of an organism?

DNA has an important role in organism forming.

DNA is nucleic acid and it has in its structure the genetic instructions on how to develop an organism. DNA can be found in almost every organism.

Explanation:

The primary function of DNA is to help the organism develop and reproduce by using a genetic code.

The sequences of DNA are converting to the messages that are used to produce proteins, the molecules which are responsible for the biggest work done in our bodies.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
