Question

What is the amount of DNA in metaphase stage of a meiocyte if a microspore of the same plant has $30pg$ DNA?

• A. $30pg$
• B. $60pg$
• C. $15pg$
• D. $120pg$

Answer 1

The correct option is B $60pg$

The meiocyte is a diploid cell where is the microspore is the haploid cell. Hence the meiocyte will have double the amount of DNA in it as compared to the microscope. In the metaphase stage of the meiocyte the DNA hasn't been segregated into the two microspore cells that and hence it contains double the amount of DNA that would be present in each.

Hence the meiocyte contains 60 pg DNA.

So the correct answer is ' 60 pg'.
