Which of the following is NOT a phenotypic test?
grigory [225]

<u>Colony morphology on agar</u> is NOT a phenotypic test.

Examples of phenotypic tests are;

  1. Antibody reaction
  2. Antibiotic resistance profile
  3. 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.

Pancreatic cells, which secrete a large amount of digestive enzymes, are labeled with radioactive leucine and then chased for se
LiRa [457]

Answer:

Option-C

Explanation:

A pulse-chase experiment which is used to study the cellular process taking place in the cells. This uses the labelled molecule which is incorporated into the cellular pathway and then the unlabeled molecules are used over time to determine how much time is required by the unlabeled molecule to replace the labelled molecule.

In the given question, the pancreatic cell which secretes the digestive enzyme known as the acinar cell is labelled with the leucine and then used unlabeled leucine.

When observed after three hours, the black spots will appear on the exterior of the cell as the protein has been synthesised by the ER and now has been secreted from the cell.

Thus, Option-C is the correct answer.
