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 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 are the products of meiosis II two things?

Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell.

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.

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 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.

Does DNA replication occur in meiosis II?

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.

Why is there no DNA replication in meiosis 2?

First thing to remember is that interphase is a stage associated with replication of DNA, and growth. Once meiosis starts, the purpose is to produce a haploid gamete. So there is no further need of replication or growth. Hence between meiosis I and meiosis II , there is no interphase.

How does DNA change during meiosis?

Recombination in meiosis. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA. …

What happens anaphase?

In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell. The protein “glue” that holds the sister chromatids together is broken down, allowing them to separate. Each is now its own chromosome. The chromosomes of each pair are pulled towards opposite ends of the cell.

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 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.
