Understanding DNA Replication Enzymes

Easy Biochemistry Nucleic Acids And Dna Replication

The process of DNA replication is crucial for cell division and the maintenance of genetic information. Enzymes play a vital role in this process, ensuring that the DNA strands are accurately copied. One of the key enzymes involved in unwinding the DNA double helix is helicase, which separates the two strands of DNA to allow replication to occur. Nucleotides, the building blocks of DNA, consist of a sugar, a phosphate group, and a nitrogenous base. In human cells, DNA polymerase is the main enzyme responsible for synthesizing a new DNA strand by adding nucleotides complementary to the template strand.

Considering the above information, which of the following statements about DNA replication is correct?

Helicase is responsible for synthesizing new DNA strands.

DNA polymerase requires a primer to initiate DNA synthesis.

Nucleotides are only composed of sugar and phosphate.

DNA replication occurs in the cytoplasm of eukaryotic cells.
