What is the structure made of guanine, cytosine, adenine, and uracil?

Back

RNA

Front

During which stage of the cell cycle is DNA replicated?

Back

Interphase

Front

Why is it important for DNA to make an exact copy during replication?

Back

If not, then there will be different instructions passed on to the new cell.

Front

What enzyme adds nucleotides to the 3' end of a DNA molecule?
