Colony morphology on agar is NOT a phenotypic test.

Examples of phenotypic tests are;

Antibody reaction
Antibiotic resistance profile
Gram staining

Explanation:

Colony morphology is the visible shape taken by a colony of microorganisms. Phenotype, on the other hand, is the external traits of an individual organism based on its genotype and environmental influence. Colony morphology is not determined by the genotype of the organisms hence can't be considered a phenotype trait.

Answer:

9 amino acids

Explanation:

A segment of a gene that has 27 nucleotides will code for 9 amino acids.

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.

number of amino acids = number of nucleotides/3

27/3 = 9 codons/amino acids
