Name an enzyme that acts on each molecule.
c. DNA

Verified step by step guidance

1. Identify the type of molecule: DNA is a nucleic acid composed of nucleotides.
2. Understand the role of enzymes: Enzymes are biological catalysts that speed up chemical reactions.
3. Determine the function needed: For DNA, common functions include replication, repair, and transcription.
4. Identify enzymes involved in these functions: DNA polymerase is an enzyme that synthesizes DNA molecules from deoxyribonucleotides, the building blocks of DNA.
5. Consider other enzymes: Other enzymes like helicase unwind the DNA helix, and ligase joins DNA fragments.

Key Concepts

DNA Polymerase

DNA polymerase is an essential enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand during DNA replication. It plays a critical role in ensuring the accuracy and fidelity of DNA replication, which is vital for cell division and genetic inheritance.

Restriction Enzymes

Restriction enzymes, also known as restriction endonucleases, are proteins that cut DNA at specific sequences. They are widely used in molecular biology for cloning, DNA analysis, and genetic engineering, allowing scientists to manipulate DNA fragments for various applications.

DNA Ligase

DNA ligase is an enzyme that facilitates the joining of DNA strands together by forming phosphodiester bonds. It is crucial in processes such as DNA replication and repair, as it seals nicks in the sugar-phosphate backbone, ensuring the integrity of the DNA molecule.
