DNA Structure and DNA Replication

Front

What are the squares with letters in DNA called?

Back

Nitrogen Bases

Front

What type of bonds join the nitrogen bases together in the DNA structure?

Back

Weak hydrogen bonds

Front

Which base pairs with Adenine in DNA?

Back

Thymine

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 function of helicase in DNA replication?

Back

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

Front

What is the leading strand in DNA replication?

Back

The leading strand is synthesized continuously in the direction of the replication fork.

Front

What is the lagging strand in DNA replication?

Back

The lagging strand is synthesized discontinuously in short segments called Okazaki fragments.

Front

What is the role of primase in DNA replication?

Back

Primase synthesizes a short RNA primer to provide a starting point for DNA synthesis.

Front

What are Okazaki fragments?

Back

Okazaki fragments are short segments of DNA synthesized on the lagging strand during DNA replication.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides, with a sugar-phosphate backbone and nitrogenous bases.
