Question

During DNA replication, a primer attaches to a template strand of DNA and begins a new strand. After the primer has attached, an enzyme extends the new strand of DNA by adding nucleotides that correspond to the nucleotide sequences in the template strand.
Which enzyme is responsible for adding nucleotides to the growing DNA molecule?
ponsible for adding nucleotides to the growing DNA molecule?
A.
DNA helicase
B.
DNA isomerase
C.
DNA polymerase
D.
DNA structase

Answer 1

Answer:

DNA polymerase

Explanation:

Prior to cell division, the DNA of that cell must be replicated in order for each daughter cell to receive the correct amount of genetic material (DNA). This process of DNA replication occurs in the Synthesis phase of Interphase. Before DNA starts replicating, the double-stranded DNA is unwound by an enzyme called DNA HELICASE to form two separate single strands.

Each of these strands serves as a template for replicating a new strand. An enzyme called DNA primase catalyzes the attachment of short nuceleotide sequences called PRIMER to the template strand in order for DNA POLYMERASE to synthesis/add new nucleotides to the growing DNA.

DNA polymerase adds nucleotides that are complementary to the ones it reads on the template strand.
