Question

Which is incorrectly paired

• A. Sry gene - X chromosome
• B. $2n-2$ - Nullisome
• C. Nucleiod - prokaryote
• D. Polytene chromosome - Drosophila

Answer 1

Answer: (A)

Sry gene - X chromosome

Testis-determining factor (TDF), also known as sex-determining region Y (SRY) protein, is a DNA-binding protein (also known as gene-regulatory protein/transcription factor) encoded by the SRY gene that is responsible for the initiation of male sex determination in humans.

So, the correct answer is 'Sry gene-C chromosome'.
