Question

Given below are two statements: Statement (I): All phylogenetic marker genes used for nematode molecular taxonomy are housekeeping genes. Statement (II): All housekeeping genes can be used as phylogenetic markers for nematode molecular taxonomy. In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are true.
• B. Both Statement (I) and Statement (II) are false.
• C. Statement (I) is true but Statement (II) is false.
• D. Statement (I) is false but Statement (II) is true.

Hint:

Remember that non-coding ribosomal DNA regions (like ITS) are the primary markers used in nematode taxonomy. Because these are not protein-coding housekeeping genes, they demonstrate that Statement I is false.

Answer 1

The Correct Option is B
