What will be the amount of DNA in meiosis 1?

How much DNA is at the end of meiosis 1?

(See figure below, where meiosis I begins with a diploid (2n = 4) cell and ends with two haploid (n = 2) cells.) In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23).

What will be the amount of DNA in meiosis 1 products?

In the first phase of the meiosis if the meiocyte contains 30pg DNA then it will be doubled in the first phase and then it will be 60pg DNA after phase. When it enters the second meiosis II then it will be divided into 4 daughter cells then 60/4=15 pg.

Does meiosis 1 change the amount of DNA?

During Meiosis, there is no change in no. of DNA molecule and chromosomes in prophase and metaphase.

How much DNA is at the end of meiosis?

At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.

What will be the amount of DNA in meiosis 2 products if your site contains 60 pg DNA in S phase?

Next comes, S phase in which DNA replicates and the amount of DNA becomes double, that is 60 pg. Now in meiosis-I, the amount of DNA becomes half and in meiosis-II, it remains same. Thus, the amount of DNA present after meiosis-II in products will be 30 pg.

What will be the amount of DNA in meiosis 2 products if DNA is 20 picogram?

What will be the amount of DNA in Meiotic II products if DNA is 20 picogram in meiocyte at G2 stage? I think the answer is 10 pg because after Meiosis I the amount of DNA in two daughter cells will be 10 pg each and then after Meiosis II its should be 10 pg in 4 haploid cells…

What will be the amount of DNA in meiosis 2 products if DNA is 20 pg in meiocyte at G2 stage?

Answer: The amount of DNA in meiosis II products would be 10 pg. The content of DNA usually doubles during the S phase of the cell cycle. So, it would increase up to 40 pg after S phase of meiocyte.

What happens to DNA in meiosis?

When recombination occurs during meiosis, the cell’s homologous chromosomes line up extremely close to one another. Then, the DNA strand within each chromosome breaks in the exact same location, leaving two free ends. Each end then crosses over into the other chromosome and forms a connection called a chiasma.

What cell is formed after meiosis 1?

However, Meiosis I begins with one diploid parent cell and ends with two haploid daughter cells, halving the number of chromosomes in each cell. Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell.
