Front

Why is DNA important for living organisms?

Back

It serves as the blueprint for traits of all living things.

Front

What term describes the method of DNA replication that uses the old strand as a template?

Back

Semi-Conservative

Front

What are the four nitrogenous bases found in DNA?

Back

Adenine, Thymine, Cytosine, Guanine

Front

What is the role of DNA polymerase in DNA replication?

Back

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

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides.

Front

What is the function of the hydrogen bonds in DNA?

Back

Hydrogen bonds hold the two strands of DNA together by pairing complementary bases.

Front

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

Back

They indicate the directionality of the DNA strand, which is important for replication and transcription.
