Amodel of the upstream region of a gene is shown. rna polymerase typically binds here before transcription begins. a mutation in the tata box region of the promoter would have which effect?

The mutation could cause serious damage in the replication process.

Explanation:

The TATA box is a DNA region that indicates the point where, processes like replication can begin. The mutation of this could cause that replication never begins, and therefore, protein synthesis is stopped. This severe complication would lead the cell to death in a short amount of time, for example.

a adaptation is when organism changes itself to fit the environment

ex. when its cold outside i wear a jacket

my google classroom is the code is 7hr2k4

~ use this opportunity to get more so you can thrive in the classroom

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.
