DNA Replication

Front

In what phase of the cell cycle does DNA replication take place?

Back

S phase

Front

Adenine bonds with ______________.

Back

Thymine

Front

What molecule's structure is represented in the drawing?

Back

A DNA molecule

Front

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

Back

Deoxyribose sugar and phosphate

Front

In a molecule of double-stranded DNA, the amount of Adenine present is always equal to the amount of ______________.

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 are the building blocks of DNA?

Back

Nucleotides, which consist of a deoxyribose sugar, a phosphate group, and a nitrogenous base.

Front

What is the function of helicase during DNA replication?

Back

Helicase unwinds and separates the double-stranded DNA into single strands.

Front

What is the significance of the antiparallel structure of DNA?

Back

The two strands run in opposite directions, which is essential for replication and function.

Front

What are the four nitrogenous bases found in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
