Back

Cell growth and preparation for DNA synthesis.

Front

What occurs during the G2 phase of the cell cycle?

Front

What is the role of DNA helicase during DNA replication?

Back

Unwinds the double helix and separates the two strands.

Front

What is the function of DNA polymerase?

Back

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

Front

What is the difference between malignant and benign tumors?

Back

Malignant tumors are cancerous, can spread, and are dangerous; benign tumors are not cancerous, do not spread, and are generally not dangerous.
