What are possible consequences of point mutations

1. silent mutation

2. non sense mutation

3. missense mutation

Explanation:

1. in a silent mutation, the substituted base will code for another codon that will get translated to the same amnio acid

2. in a non sense mutation, the substituted base will code for a STOP codon that would cause the production of a faulty, usually non functional protein, missing some amnio acids.

3. in a missense mutation, the substituted codon codes for a different amino acid and this can have a small to great effect on the product protein based on its function. eg: sickle cell anemia where you've substituted a polar amino acid with a non polar one, thus causing severe consequences

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.

it takes hundreds of years to become stable.

if you have another question lmk.
