If a DNA molecule is found to be composed of 35% thymine, what percentage of cytosine would be expected, and why?
-Dominant- [34]
We use Chargaff's rule to get the answer. [A] + [G] = [C]+ [T].    [A] + [G] + [C] + [T] = 100% Where is A is Adenine, G is Gaunine, T is Thymine and C is Cytosine. In DNA, Adenine always pairs with Thymine, and Guanine always pairs with Cytosine. Therefore if Thymine is 35%, then Adenine will also be 35% to make 70% in total. The remaining percentage will be 100% - 70% = 30%. The 30% will be shared equally among Cytosine and Guanine, at 15% each. Therefore Cytosine will be 15%

How does the anaphase stage differ in the two phases of meiosis?
Ronch [10]

The answer is c. Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.


Meiosis is a cell division which results in the reduction of chromosome number by half (from diploid to haploid) in daughter cells. It consists of meiosis I and meiosis II. 

In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicates which are present as pairs of sister chromatids. When comes to separation, homologous chromosomes separates only, but not sister chromatids. Homologous chromosomes are present only in meiosis I.

 In anaphase II, since the cell is haploid, there are 23 chromosomes in duplicates, which are present as sister chromatids. So, in this phase, sister chromatids are those who separates.
