DNA Replication

Front

What is the structure of a DNA molecule?

Back

A DNA molecule is structured as a double helix.

Front

What type of bond joins nitrogenous bases in DNA?

Back

Nitrogenous bases are joined by hydrogen bonds.

Front

What holds the two strands of the DNA double helix together?

Back

The two strands of the DNA double helix are held together by hydrogen bonds.

Front

What is the result of DNA replication?

Back

DNA replication results in two DNA molecules, each with one new strand and one original strand.

Front

What forms the sides (backbone) of the DNA ladder?

Back

The sides of the DNA ladder are formed by deoxyribose sugar and phosphate.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine, thymine, cytosine, and guanine.

Front

What base pairs with adenine in DNA?

Back

Thymine pairs with adenine in DNA.

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.

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 significance of the antiparallel structure of DNA?

Back

The antiparallel structure of DNA allows for complementary base pairing and proper replication.
