A single nucleotide changes in CCG which will result in missense mutation can be many possibilities.

Explanation:

Missense mutations  

CCG codes for Proline amino acid

•Mutation in first nucleotide codes for  

UCG specifically encodes Serine

ACG specifically encodes Threonine  

GCG specifically encodes Alanine                              

                                                                                      Missense mutation  

•Mutation in second nucleotide specify for coding

CUG specifically encodes Leucine

CAG specifically encodes Glutamine  

CGG specifically encodes Arginine

•Mutation in Third Nucleotide will not result in missense mutation because any point mutation in third nucleotide of codon will encode same amino acid i.e Proline.  

as many times as you want

hey, what do you need . just post the question and i may be able to you : )
