Answer:

Step-by-step explanation:

The following Arrangements of codons in the DNA sequence can give rise to the polypetide chain combination of valine-methionine -phenylalanine

GUUAUGUUU

Val-Met-phe

GUUAUGUUC

Val-met-phe

GUCAUGUUU

Val-met-phe

GUCAUGUUC

Val-met-phe

GUAAUGUUU

Val-met-phe

GUAAUGUUC

Val-met-phe

GUGAUGUUC

Val-met-phe

GUGAUGUUU

Val-met-pee

The amino acid valine is specific for by 4 different codon which include GUU,GUC,GUA,GUG

Methionine is specific by AUG and it is refer to as the start codon while phenylalanine is specified for by 2 different codon UUU,UUC therefore in all 8 different base sequence can specify for the three amino acids.
