Question

review the passage about the effects of the krt13 gene mutation.
keratin are strong proteins that provide structure and protection for many tissues in the human body. for example, the tissue on the inside of the mouth, called epithelium (ep-i-theel-i-um), is protected by a tough layer made of many types of keratin proteins connected together. one type of keratin protein is encoded by the krt13 gene.
a certain person had a mutation in the krt13 gene. compared to the krt13 gene without a mutation, the mutated krt13 gene encoded a form of the keratin protein with a different structure.
this different form of the keratin protein could not connect to other keratin proteins. the person with the mutation had mouth epithelium that was easily damaged by simple activities like eating and brushing teeth.
complete the sentence.
the mutation caused the krt13 gene to encode a form of the keratin protein that could not connect with other keratin proteins. so, compared to a person without the mutation, this the persons mouth epithelium was ______.
more easily damaged
less easily damaged

Explanation:

The passage states that the mutated keratin protein couldn't connect to others, and the person's mouth epithelium was easily damaged. So, compared to a non - mutated person, the damaged - easily property is more.

Answer:

more easily damaged
