Match

Match these enzymes with their function in DNA replication: DNA polymerase, endonuclease, helicase, and ligase.

Check the DNA for errors and attempt to correct them.

Build new strands of nucleotides through complementary base pairing to the original strand.

Break the hydrogen bonds holding two strand of nucleotides together.

Attach nucleotides together within a strand by creating a covalent bond between the deoxyribose of one nucleotide and the phosphate group of the next nucleotide.

endonucleases

DNA polymerase

helicase

ligase

Multiple Choice

Question image

Use the models (A & B) to answer the following question. Which model and explanation BEST represents semiconservative replication?

1

Model A because it shows one original strand and one complimentary strand in each product (F1) DNA molecule.

2

Model A because none of the DNA molecules produced (F2) are identical to the parent DNA molecule.

3

Model B because one F1 strand is identical to the parent molecule and the other is not.

4

Model B because one of the F2 molecules contains the original strands of the parent molecule and the other three do not.
