it the amino acid sequences in gorillas and humans are similar , are the nucleotide sequences of thir DNA also similar? why?

This is a generalization, but in general (I'm trying to emphasize this) there is more diversity for SIMILAR amino acid sequences than their corresponding nucleotide sequences.
But for IDENTICAL amino acid sequences in closely related organisms the opposite would probably be true, due to the fact that some amino acids have more than one possible codon.

DNA is the master molecule of the cell. It contains all the codes for all the proteins in an organism (genes). Proteins are made up of amino acids. Therefore, if the protein's amino acid sequences in organisms are similar, then they would have to have similar DNA sequences to produce these proteins.

They are, but they don't have to be. If the amino acid sequences were the same by chance, the DNA sequences could be quite different since there are often several ways to encode one amino acid.
