• Ionic bond

Rosalind Franklin

• Determined that, in a sample of DNA, the percentage of A is equal to T and G is equal to C

• Figured out structure of DNA was a double helix

• Woman who generated x-ray images of DNA, she provided Watson and Crick with key data about DNA

• Discovered that the transforming factor was DNA

Primase

• -a weak bond that connects the two strands of DNA

• a segment on DNA that gives instructions to make one protein

• a strong bond formed when atoms share one or more pairs of electrons

• "the initiator". Tells DNA polymerase where to add the nucleotides
