Answer 1

Here are the matches between Column A and Column B:

1. **antiparallel**: c. When two molecules that are side by side but run in opposite directions.
2. **DNA ligase**: f. Enzyme that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond. It plays a role in repairing single-strand breaks in DNA in living organisms.
3. **DNA polymerase**: b. Enzyme that synthesizes DNA molecules from deoxyribonucleotides.
4. **lagging strand**: i. Strand that requires a slight delay before undergoing replication, and it must undergo replication discontinuously in small fragments.
5. **leading strand**: g. The template strand of the DNA double helix that is oriented so that the replication fork moves along it in the 3' to 5' direction.
6. **Okazaki fragments**: h. Short sequences of DNA nucleotides which are synthesized discontinuously and later linked together by the enzyme DNA ligase to create the lagging strand during DNA replication.
7. **replication fork**: a. The area where the replication of DNA will actually take place.
8. **RNA primer**: d. RNA that initiates DNA synthesis.
9. **semiconservative**: e. Relating to or denoting replication of a nucleic acid in which one complete strand of each double helix is directly derived from the parent molecule.
