DNA Polymerase: Synthesis of DNA Strands DNA polymerase is an enzyme responsible for the synthesis of new DNA strands during DNA replication. It adds complementary nucleotides to the existing DNA template strand, following the base-pairing rules (A with T and C with G), to create two identical DNA molecules from one original strand. DNA polymerase is essential for the accurate and efficient replication of DNA and plays a crucial role in maintaining the genetic integrity of an organism.
Helicase: Unwinding of DNA Helix Helicase is an enzyme that unwinds the double-stranded DNA helix by breaking the hydrogen bonds between the complementary base pairs. This unwinding action is a crucial step in DNA replication, as it separates the two DNA strands and exposes the template strands for replication by DNA polymerase. Helicase ensures that the DNA molecule can be duplicated and transcribed for various cellular processes like replication, transcription, and repair.
Ligase: Joins Together Short DNA Segments DNA ligase is an enzyme that plays a key role in the process of DNA replication and repair. It is responsible for joining together the short DNA fragments, known as Okazaki fragments, on the lagging strand during DNA replication. These fragments are synthesized in the opposite direction of the replication fork. DNA ligase catalyzes the formation of phosphodiester bonds between the sugar-phosphate backbones of adjacent DNA fragments, creating a continuous and functional DNA strand. In addition to replication, DNA ligase is also involved in DNA repair processes, ensuring the integrity of the genetic material.

Enzymes and their Functions:
DNA polymerase: Synthesis of DNA Strands
- DNA polymerase is an enzyme responsible for the synthesis of DNA strands.
- It catalyzes the addition of nucleotides to the growing DNA strand during DNA replication.
- It reads the template DNA strand and adds complementary nucleotides to form a new DNA strand.
- DNA polymerase plays a crucial role in maintaining the integrity and fidelity of the DNA sequence during replication.
Helicase: Unwinding of DNA helix
- Helicase is an enzyme that unwinds the double-stranded DNA helix during DNA replication.
- It breaks the hydrogen bonds between the base pairs, separating the DNA strands and creating a replication fork.
- This unwinding process is necessary for DNA replication as it exposes the template strands for DNA polymerase to synthesize new strands.
Ligase: Joins together short DNA segments
- Ligase is an enzyme that joins together short DNA segments, specifically the Okazaki fragments on the lagging strand during DNA replication.
- It catalyzes the formation of phosphodiester bonds between the adjacent nucleotides, sealing the gaps and creating a continuous DNA strand.
- Ligase plays a significant role in completing the synthesis of the lagging strand during DNA replication.
Explanation:
The correct match of enzyme with its related function is option 'D' - All of these.
- DNA polymerase is responsible for the synthesis of DNA strands during DNA replication.
- Helicase unwinds the DNA helix to expose the template strands for replication.
- Ligase joins together short DNA segments, ensuring the completion of the lagging strand synthesis.
- Therefore, all three enzymes are involved in different steps of DNA replication and collectively play crucial roles in maintaining the integrity and fidelity of the DNA sequence.
