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 DNA amount in meiosis 2 products of 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 will be the amount of DNA in meiosis 2 products?
Both the cells undergo further division to form 4 haploid cells during the process of meiosis II. That means the content is further reduced to half i.e 15 pg DNA in each cell(M II). So, the correct answer is option C, 15pg.
What will be the amount of DNA in meiosis 2 products if your site contains 36 pg DNA in G1 phase?
In G1 phase, 30 pg of DNA is present. 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 your site contains 60 pg DNA in S phase?
When it enters the second meiosis II then it will be divided into 4 daughter cells then 60/4=15 pg. Then there will be 15pg in the individual cells. After the cell division individual daughter cells contain 15pg DNA.
What happens to DNA in meiosis 2?
Meiosis II begins with the 2 haploid cells where each chromosome is made up of two connected sister chromatids. DNA replication does NOT occur at the beginning of meiosis II. The sister chromatids are separated, producing 4 genetically different haploid cells.
What happens to the amount of DNA during meiosis?
Meiosis I separates half of the chromosomes into one daughter cell and half into the other, so the amount of DNA per cell becomes X/2. Then meiosis II splits each chromosome in half (into separate chromatids), so the amount of DNA per cell now becomes X/4.
What is the quantity of DNA in telophase if G2 has 40pg DNA?
After G2 phase, the cell under goes meiosis I that produces two daughter cells with chromosome number and DNA content reduced to half. Thus, each of the two new cells will have chromosome number = n = 10 chromosomes and DNA content = 2C= 40 picogram.
What will be the amount of DNA in g1?
DNA content in g1 phase is 30 pgm.
How much DNA is present in each phase of meiosis?
It starts with a diploid cell that has undergone chromosomal DNA replication: 2N chromosomes, 4X DNA content. Two successive divisions, with no additional DNA replication, results in 4 haploid gametes: 1N chromosomes, 1X DNA content. Meiosis sets the stage for Mendelian genetics.
What will be the amount of DNA in a somatic cell at G2?
These cells are produced from the body and act in the growth and development of the body. If its meiotic product has 20 picograms of DNA then the content of DNA in a somatic cell will be 80 picograms at the G2 phase of the cell cycle where DNA replication takes place.
How many chromosomes are there after meiosis 2?
During meiosis II, each cell containing 46 chromatids yields two cells, each with 23 chromosomes. Originally, there were two cells that underwent meiosis II; therefore, the result of meiosis II is four cells, each with 23 chromosomes.
What will be the amount of DNA in a pollen grain?
So, if the diploid mother cell has 16 picograms of DNA, the quantity of DNA in haploid pollen grain is half of that, or 8 picograms. Therefore, the correct answer is 8 pg which is option ‘C’.
What is the role of meiosis 2?
The second round of cell division is meiosis II, in which the goal is to separate sister chromatids. … Telophase II: Newly forming gametes are haploid, and each chromosome now has just one chromatid.
How many cells does meiosis produce 200 cells?
So, the correct answer to the question is option C “50, 50”. Note: Meiosis is a type of cell division that lessens the number of chromosomes in the parent cell by half as well as they develop four gamete cells.
