U

HideShow resource information
What do nucleotides join together to form?
Polynucleotides
1 of 5
What can two polynucleotides join together to form?
Double Helix
2 of 5
Typical Pairings
AT, CG (A or G always with T or C)
3 of 5
What does DNA do before cell division?
Replicates itself so that each new cell has the full amount of DNA.
4 of 5
How can it copy itself?
DNA helicase breaks the h20 bonds between the polynucleotide strands. Free DNA join to the exposed bases. Joined together DNA polymerase. One strand from original and one from a new strand
