Question

A cell has 10 picogram of DNA which undergone meiosis. What will be the amount of DNA in the product of meiosis I and meiosis II?

• A. 10 pg and 10 pg respectively
• B. 10 pg and 5 pg respectively
• C. 5 pg and 5 pg respectively
• D. 5 pg and 10 pg respectively

Answer 1

The correct option is B 10 pg and 5 pg respectively

• As the cell enters meiosis 1, it's DNA replicates in S phase and then reduces to half when the cell splits into two. Hence, the amount of DNA remains 10 pg.
  
• During meiosis 2, there is no DNA replication but only division between cells, leading to 5 pg of DNA in all four daughter cells.
  

So, the correct option is '10 pg and 5 pg respectively'
