Question #1
The 'Philadelphia chromosome', associated with Chronic Myelogenous Leukemia (CML), is the result of a reciprocal translocation between chromosomes:
A. 9 and 22
B. 11 and 14
C. 14 and 21
D. 8 and 14

Correct Answer: Option A


Explanation:
The Philadelphia chromosome is a specific genetic abnormality found in the bone marrow cells of most patients with Chronic Myelogenous Leukemia (CML). It is formed by a reciprocal translocation between the long arms of chromosome 9 and chromosome 22, denoted as t(9;22). This translocation fuses the BCR gene on chromosome 22 with the ABL1 gene on chromosome 9, creating a mutant BCR-ABL1 fusion protein with constitutive tyrosine kinase activity, driving uncontrolled cell division.

Question #2
Which of the following is NOT a plant hormone?
A. Cytokinin
B. Gibberellin
C. Thyroxine
D. Auxin

Correct Answer: Option C


Explanation:
Thyroxine is an animal hormone secreted by the thyroid gland, regulating metabolism. Auxin, gibberellin, cytokinin, abscisic acid, and ethylene are plant hormones (phytohormones). Plant hormones control growth, development, and responses to environment. Thyroxine contains iodine and affects basal metabolic rate. Thus, thyroxine is unrelated to plant physiology.
