DNA Replication,Transcription & Translation

During DNA replication, the enzyme helicase (blue stucture) is responsible for what action?

• keeping the double helix of the DNA molecule tightly locked together

• unzipping the DNA molecule

After DNA is unzipped, which enzyme is responsible for base pairing the nucleotides to make a copy (complementary strand) of the DNA?

• helicase

• DNA polymerase

What makes up the sides of the DNA molecule

• phosphate group

• nitrogenous base

• deoxyribose sugar

Which structures make up the 'rungs' of the DNA molecule​ (a)
