8 How do I write the complimentary DNA strand??

9 Remember Chargaff’s Base Pairing Rules?? Adenine (A) pairs with Thymine (T) Guanine (G) pairs with Cytosine (C) DNA Strand: Complimentary DNA Strand: TGCGCGTTAAGT ACGCGCAATTCA

13 How do you make more DNA?

15 WHERE DOES DNA REPLCATION OCCUR? S Phase occurs during interphase of the cell cycle Takes place in the nucleus of eukaryotes

16 How does DNA Replication work? How does your DNA go from 1 DNA strand  2 identical DNA strands

17 Matching Cards
