DNA Replication Quiz

How do the nitrogenous bases pair in DNA?

• Adenine pairs with cytosine and guanine pairs with thymine (A-C, G-T)

• Adenine pairs with thymine and cytosine pairs with guanine (A-T, C-G)

• Adenine pairs with guanine and cytosine pairs with thymine (A-G, C-T)

• Adenine pairs with uracil and cytosine pairs with thymine (A-U, C-T)

What is the importance of DNA replication in cell division?

• DNA replication is crucial for cell division as it ensures that each daughter cell receives an identical copy of the genetic material.

• DNA replication occurs only in prokaryotic cells during binary fission.

• DNA replication is a process that occurs after cell division to repair damaged DNA.

• DNA replication is not necessary for cell division and can occur independently.

What are the four nitrogenous bases found in DNA?

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

• Adenine (A), Uracil (U), Cytosine (C), Guanine (G)

• Adenine (A), Thymine (T), Cytosine (C), Uracil (U)

• Guanine (G), Thymine (T), Cytosine (C), Adenosine (A)

What are the building blocks of DNA?

• Amino acids

• Nucleotides

• Fatty acids

• Monosaccharides

What is the function of the sugar-phosphate backbone in DNA?

• It provides energy for DNA replication.

• It acts as a template for RNA synthesis.

• It provides structural support to the DNA molecule, holding the nucleotides together.

• It facilitates the binding of proteins to DNA.

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

• It allows for the complete destruction of old DNA strands.

• It ensures that each new DNA molecule contains one original strand and one newly synthesized strand, preserving genetic information.

• It prevents mutations from occurring during DNA synthesis.

• It enables the rapid replication of DNA without any errors.

What is the function of DNA Polymerase?

• DNA Polymerase is responsible for repairing damaged DNA strands.

• DNA Polymerase is the enzyme that adds free nucleotides to the growing DNA strand during replication.

• DNA Polymerase helps in the transcription of RNA from DNA.

• DNA Polymerase is involved in the synthesis of proteins from amino acids.

What is the role of DNA Helicase in DNA replication?

• DNA Helicase is responsible for unwinding and unzipping the double-stranded DNA, allowing the replication process to occur.

• DNA Helicase synthesizes new DNA strands by adding nucleotides to the growing chain.

• DNA Helicase repairs damaged DNA by removing and replacing nucleotides.

• DNA Helicase acts as a primer to initiate the DNA replication process.

What is the process of DNA replication?

• DNA replication is the process by which a DNA molecule makes a copy of itself, resulting in two identical DNA molecules, each containing one old strand and one new strand.

• DNA replication occurs only during cell division and involves the separation of the two strands of DNA.

• DNA replication is the process of converting RNA into DNA through reverse transcription.

• DNA replication is the synthesis of proteins from amino acids.
