The answer is T A A C G T.
Replication is a process in which DNA molecule is copied, and thereby two identical DNA molecules are produced. Complementarity is achieved through interactions between nucleobases. In the DNA, base complements are adenine - thymine (A-T) and guanine - cytosine (G-C).
So, free nucleotides will add in the following order <span>T A A C G T:

Answer:
The light-dependent reactions take place in the thylakoid membranes in the granum (stack of thylakoids), within the chloroplast. Figure: The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions).
Explanation:
Each stack is called a granum (the plural is grana) which is suspended in a fluid called stroma. The light-dependent reactions occur in the grana; the light-independent reactions take place in the stroma of the chloroplasts.
