Front

What connects one nucleotide to another along a strand of genetic material?

Back

Each one with one new strand and one original strand.

Front

Which 2 molecules form the sides (backbone) of the DNA ladder?

Back

Deoxyribose sugar and phosphate.

Front

Which forms the steps or 'stairs' of the DNA ladder?

Back

Nitrogen base.

Front

Which of the following best describes a DNA molecule?

Back

Front

What is the role of DNA polymerase in DNA replication?

Back

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

Front

What is the function of helicase during DNA replication?

Back

It unwinds the DNA double helix, separating the two strands.

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 crucial for replication and transcription.

Front

What is a replication fork?

Back

The Y-shaped region where the DNA double helix is separated into two single strands during replication.

Front

What are Okazaki fragments?

Back

Short segments of DNA synthesized on the lagging strand during DNA replication.
