DNA Replication

The enzyme that splits open the DNA creates what's called a fork - where the DNA separates into the lagging strand and the ______ strand.

• leading

• leveraging

• Okazaki

• ligase

Sometimes, DNA is called "semi-conservative." Why might this be?

• The old strand is "conserved" and used to make the new strands

• Uracil is "conserved" in that it is only used to make the new strands

• ATP is "conserved" via the usage of facilitated diffusion

• Ligase is "conserved" in that it is denatured by the process

DNA replication turns one strand of DNA into two new strands of DNA. What percent of each new strand is the old strand?

• Half of each new DNA is the old DNA

• The old strand of DNA was digested, so none

• The new DNA is entirely made up of the old DNA

• About every sixth base comes from the old DNA
