At Interphase, there is only one cell, but
after cytokinasis there are two identical
cells Before mitosis the cell need to store
enough. During this period of time, there
is intense cellular activity. The cell grows
in size. The length of the grow phase

purine and pyrimidine base-pairing in DNA/RNA
Purines are double-ring molecules (bases), while pyrimidines are single-ring molecules (bases), and all DNA
is made up of just four chemicals:(A) Adenine (purine), (T) Thymine (pyrimidi
