What are the base pairs in DNA and their complementary pairs?

Back

A-T (Adenine-Thymine), G-C (Guanine-Cytosine)

Front

What is the complementary sequence for the DNA strand AAGCTAT?

Back

TTCGATA

Front

What is a nucleotide composed of?

Back

A nucleotide is composed of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is the enzyme responsible for synthesizing new DNA strands by adding nucleotides complementary to the template strand.

Front

What are the components that make up the sides of the DNA ladder?

Back

The sides of the DNA ladder are made of alternating sugar and phosphate groups.

Front

What is the structure of DNA described as?

Back

DNA is described as a double helix.

Front

What is the function of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix, separating the two strands to allow replication.

Front

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

Back

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

Front

What is the difference between leading and lagging strands during DNA replication?

Back

The leading strand is synthesized continuously in the same direction as the replication fork, while the lagging strand is synthesized in short segments (Okazaki fragments) in the opposite direction.

Front

What is the role of RNA primers in DNA replication?

Back

RNA primers provide a starting point for DNA polymerase to begin synthesis of the new DNA strand.
