No. of DNA molecule =2 ; No of chromosomes per cell is 2. Now the four cells formed have half the number of chromosome to that of the parent cell, and that is the result of meiosis. In the figure initial chromosome number is 4 (2n=4). Then the changes in no. of DNA molecules and chromosomes during mitosis and meiosis is summarised in the table.

The procedure lower limit of quantitation (LLOQ) of 5 pg of DNA per mg of PS or 250 pg of DNA per 50 mg dose of PS was determined from DNA spike recovery curves using the acceptance criteria of 70–130% recovery with % CV ≤ 25%. Seven pharmaceutical-grade lots of PS were evaluated and the detectable amount of resDNA was below the LLOQ.

Thus, although the total chromosome volume per cell was closely correlated (r greater than 0.97) with 4C DNA amount in somatic and meiotic cells, the density of DNA in metaphase chromosomes was significantly lower in meiocytes (0.131 pg/micrometers3) than in somatic metaphase cells (0.19 pg/micrometers3).

E.Coli as reference genome is an ideal model system to identify amplification bias introduced via technology used.
How much DNA are there in the human body? - Quora
The synthesis phase (S): The DNA is replicated during this phase. In other words, an identical copy of all the cell’s DNA is made. This ensures that each new cell has a set of genetic material identical to that of the parental cell. DNA replication will be further discussed in lesson 5.3.

How much DNA is there in a bacterial cell?
The amount of DNA per cell of a particular species is measured in cells found at various stages of meiosis, and the following amounts are obtained: Amount of DNA per cell 3.7 pg 7.3 pg 14.6 pg Match the amounts of DNA above with the corresponding stages of the cell cycle (a through f). You may use more than one stage for each amount of DNA.

C-value is the amount, in picograms, of DNA contained within a haploid nucleus (e.g. a gamete) or one half the amount in a diploid somatic cell of a eukaryotic organism. In some cases (notably among diploid organisms), the terms C-value and genome size are used interchangeably; however, in polyploids the C-value may represent two or more genomes contained within the same nucleus.
