Front

What is the role of DNA helicase during replication?

Back

DNA helicase unwinds and unzips the DNA double helix.

Front

What type of sugar is found in DNA?

Back

The sugar found in DNA is deoxyribose.

Front

What is the process by which genetic material is duplicated before cell division?

Back

The process is called DNA replication.

Front

What type of bond joins nitrogenous bases in DNA?

Back

Nitrogenous bases are joined by hydrogen bonds.

Front

What does the acronym DNA stand for?

Back

DNA stands for Deoxyribonucleic acid.

Front

What are the four nitrogenous bases found in DNA?

Back

The four nitrogenous bases are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What base pairs with adenine in DNA?

Back

Thymine pairs with adenine in DNA.

Front

What is the structure of DNA described as?

Back

DNA is described as a double helix.

Front

What is the function of DNA polymerase in replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the significance of the 5' and 3' ends of a DNA strand?

Back

The 5' and 3' ends indicate the directionality of the DNA strand, which is important for replication and transcription.
