DNA Repair Quiz

What is DNA repair?

• Process of identifying and correcting damage to DNA molecules.

• Process of identifying and amplifying damage to DNA molecules.

• Process of identifying and preventing damage to DNA molecules.

• Process of identifying and enhancing damage to DNA molecules.

What are the subtopics of DNA repair?

• base excision repair, nucleotide excision repair, mismatch repair, double-strand break repair

• transcription repair, replication repair, recombination repair

• protein repair, enzyme repair, cell repair

• RNA repair, protein repair, lipid repair

What is DNA damage?

• Any alteration in the structure or sequence of DNA molecules.

• A method of DNA replication.

• A process that repairs DNA molecules.

• A type of genetic mutation.

What is mismatch repair?

• Process that introduces errors during DNA replication

• Cellular process that corrects errors during RNA transcription

• Cellular process that corrects errors during protein synthesis

• Cellular process that corrects errors during DNA replication

What is nucleotide excision repair?

• Nucleotide excision repair is a DNA repair mechanism that removes bulky DNA lesions.

• Nucleotide excision repair is a mechanism that repairs RNA instead of DNA.

• Nucleotide excision repair is a type of repair that only works on small DNA lesions.

• Nucleotide excision repair is a process that adds extra nucleotides to damaged DNA.

What is base excision repair?

• Base excision repair is a process that removes entire nucleotides from the DNA strand.

• Base excision repair is a process that repairs double-stranded DNA breaks.

• Base excision repair is a repair mechanism that only corrects large, helix-distorting DNA lesions.

• Base excision repair is a DNA repair mechanism that corrects small, non-helix-distorting DNA lesions such as damaged or incorrect bases.

What is double-strand break repair?

• Process by which cells repair breaks that occur in both strands of the RNA double helix.

• Mechanism by which cells repair breaks that occur in the RNA double helix.

• Mechanism by which cells repair breaks that occur in both strands of the DNA double helix.

• Process by which cells repair breaks that occur in only one strand of the DNA double helix.
