Predict the most likely effect of a two-nucleotide deletion in the middle of the intron located between exons 4 and 5 on the structure of protein A. Justify your answer.

It is likely that this change has no effects on the protein function.

Explanation:

In eukaryotes, genes are composed of coding (exons) and non-coding  (introns) sequences. Since introns are not transcribed into messenger RNA, mutations affecting these sequences generally are neutral; however, it is important to note that introns may regulate gene expression  

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.
