Two eukaryotic proteins were found to be very similar except for one domain that was very different. Which of the following processes is most likely to have contributed to this phenomenon?

A. multiple random mutations within specific exons of the gene.

B. use of different transcriptional activators.
differential acetylation of specific histone proteins prior to transcription.

C. differences in pre-mRNA splicing that results in an altered pattern of exon inclusion.

D. All of the above.

"The differences in pre-mRNA splicing that results in an altered pattern of exon inclusion" is most likely to have contributed to this phenomenon.

Option: C

Explanation:

The expression of the eukaryotic gene requires several stages and can be regulated by several of them. Different genes are controlled at different locations and it is not unusual for a gene to be controlled at multiple steps, especially a significant or powerful one.

explanation:

i was told this before by a teacher, so yeah

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
