A part of an mRNA has the sequence CCG. Which change to this sequence
Flauer [41]

Answer:

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.
