Alleles
I had bio a while ago though so I could be wrong...
Interphase: You could not distinguish any parts of the cell.
Prophase: You could clearly see the chromosomes throughout the cell.
Metaphase: The chromosomes where lines up in the middle of the cell.
Anaphase: You could see the chromosomes were separated to ether side of the cell.
Telophase: The entire cell was separated to each side but was not split into its own cell.
Cytokinesis: In this step the cell had totally separated and there was now two separate daughter cells.
Im not sure but i believe it could be C
Answer: <u>Guanine
</u>
According to Chargaff's rule, the base pairing in the DNA and RNA is fixed. Adenine always pairs with Thymine in DNA and Uracil in RNA. Guanine pairs up with cytosine. This complementary base pairing is universal and constant. That's why amounts are also equal. It means if cytosine is 20% in any DNA sample, then amount of guanine would be 20% as well.
