DNA Replication

Front

What is DNA replication?

Back

DNA replication is the process by which a DNA molecule makes an exact copy of itself.

Front

True or False: The new DNA strand formed after DNA replication is an exact copy of its parent strand.

Back

True

Front

What are the end products of DNA replication?

Back

DNA replication results in 2 DNA molecules that each contain one strand of the original DNA.

Front

What enzyme is responsible for joining Okazaki fragments during DNA replication?

Back

Ligase.

Front

What are the components of a DNA nucleotide?

Back

A DNA nucleotide consists of deoxyribose sugar, a phosphate group, and a nitrogenous base.

Front

Which of the following is NOT a component of a DNA nucleotide? Cholesterol, Deoxyribose, Phosphate group, Nitrogenous base?

Back

Cholesterol.

Front

What is the role of helicase in DNA replication?

Back

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

Front

What is the function of DNA polymerase?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the difference between replication, transcription, and translation?

Back

Replication copies DNA, transcription converts DNA to RNA, and translation synthesizes proteins from RNA.

Front

What is the significance of the semi-conservative nature of DNA replication?

Back

Each new DNA molecule consists of one old strand and one new strand, ensuring genetic continuity.
