Which level of taxonomy divides its organisms based on DNA sequences instead of structural similarities? *
A Domain
B Kingdom
C Genus
O D Species

D Species

Explanation:

Living organisms have been organized into groups using the Kingdom to Species classification. Kingdom level represents the least specific while Species level represents the most specific. Prior to the discovery of DNA, classification of organisms has been based on structural similarities i.e. organisms that look similar are classified into the same species.

However, the discovery of DNA, put a stop to the erroneous classification of organisms based on structural similarities as there were many exceptions to this. Since members of the same species have a nearly identical DNA, it is used to divide its organisms based on DNA sequences

instead of structural similarities.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
