Question

The DNA content of a gametic cell in a sexually reproducing plant is 1 C. What will be the DNA content of a sporogenous cells in the anther after $G_2$ phase ?

• A. C
• B. 2C
• C. 4C
• D. $\frac{1}{2}C$

Answer 1

The correct option is A C

In G${}_1$ phase the DNA is C, in S phase it will replicate and form 2C, it will remain same till G${}_2$ phase. After G${}_2$ phase the cells will divide into two and divide the DNA into two equal halves.

So, the correct answer is ' A'.
