Repair of DNA damage in eukaryotic cells involves which of the following processes? 1. Detection of DNA damage 2. DNA synthesis 3. Excision of DNA damage 4. Transcription of repaired DNAGroup of answer choices1 and 21, 3, 41, 2, 32, 3, 4All of 1-4
Solution
The repair of DNA damage in eukaryotic cells involves the following processes:
-
Detection of DNA damage: The cell has mechanisms to detect any damage in the DNA structure. This is the first step in the repair process.
-
Excision of DNA damage: Once the damage is detected, the damaged section of the DNA is removed or "excised". This is done by various enzymes that recognize and cut out the damaged DNA.
-
DNA synthesis: After the damaged section is removed, new DNA is synthesized to replace the excised section. This is done by DNA polymerase, an enzyme that synthesizes new DNA strands.
-
Transcription of repaired DNA: Once the DNA has been repaired and is back to its normal structure, it can be transcribed to produce RNA and then proteins.
So, the correct answer is "All of 1-4".
