Mutations and DNA replication errors can alter base sequences, thereby potentially creating or eliminating recognition sites. Group of answer choices True False

The given statement is true.

Explanation:

An error at the time of the replication of DNA or mutation can either result in the addition or deletion of DNA bases that eventually makes a substantial change in the sequence of DNA, and thus, will exhibit a substantial influence on the recognition sequence because of which one can witness a change in the site of recognition.  

This variation witnessed in the DNA's recognition site can be evaluated by treating the mutated DNA with the restriction enzymes that exhibit a uniqueness for the restriction sites. Afterward, by going through the process of gel electrophoresis one can witness the change in the number of bands of DNA showing variation in the restriction sites.  

A dichotomous key is complete when each organism stands alone is the correct answer.

Explanation:

Dichotomous key helps scientists and biologists to known the identity of the various unknown things present in a natural world such as mammals, trees, fish, rocks, reptiles.

This tool is used to recognize and classify an organism based on their characteristics and it helps to provide a correct name to an organism that differentiates the organism from the other objects.

The dichotomous key identifies the individual species, objects, or organism with its scientific name.
