DNA and DNA Replication

Front

What is the process in which DNA makes an exact copy of itself?

Back

Replication

Front

What sequence of DNA bases would pair with the partial strand ATG TGA CAG?

Back

TAC ACT GTC

Front

What determines the code of a DNA molecule?

Back

The order (sequence) of the nitrogen bases.

Front

What type of bond joins nitrogenous bases in DNA?

Back

Hydrogen bonds.

Front

In which phase of the cell cycle does DNA replication occur?

Back

S phase.

Front

What are the four nitrogenous bases in DNA?

Back

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

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 significance of the double helix structure of DNA?

Back

The double helix structure allows for the efficient packing of DNA and provides stability.

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 difference between leading and lagging strands during DNA replication?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short segments called Okazaki fragments.
