1) In an important experiment with E. coli Meselson and Stahl

established that during DNA replication, each of the two strands that

make up the double helix were used as a template for the new strands

of DNA The scientists described the replication method as semi-

conservative. What does this indicate?

ON

cases

The two original DNA strands the parental strands.

woulde-be used as templates to synthesize new

strands

After base pairing both copies of the new DNA

B) molecules would be a mix of alternating segments of

old and new DNA

Base pairing would result in two double-stranded

DNA molecules that would include one parental or

Old strand and one daughter on new strand

The two ne synthesized strands, the daughter

D strands would besepair with each other one to form

Snea-old strand and on a new strand
