Answer:
9 amino acids
Explanation:
A segment of a gene that has 27 nucleotides will code for<u> 9 amino acids.</u>
<em>Each codon on the gene potentially represents an amino acid and a codon is made up of 3 nucleotides each. Hence, in order to find out the total number of amino acids that a gene segment with 27 nucleotides can code for, the number of nucleotides should be divided by 3.</em>
     number of amino acids = number of nucleotides/3
                      27/3 = 9 codons/amino acids
 
        
             
        
        
        
Answer: The principle of dominance states that some alleles are dominant and others are recessive. An organism with a dominant allele for a particular form of a trait will always exhibit that form of the trait. An organism with a recessive allele for a particular form of a trait will exhibit that form only when the dominant allele for the trait is not present.
Explanation:
   Dominant                 T     t
     TT Tt Tt             T   TT  Tt
  Recessive=           t   Tt   tt
         tt
