Preguntas del test (11)
1Which of the following can cause double strand breaks in the DNA?
- AIonising radiation
- BMeiosis
- CChemicals
- DDNA replication errors
2What are Chromosome Fragile Sites?
- ASites where double strand breaks are likely to occur
- BSites that can be easily split accidentally by protein machinery
- CSites that are likely to warp during heat shock
3Chromosome fragile sites are thought to be caused by difficulties during meiosis
- AVerdadero
- BFalso
4What does NHEJ stand for?
- ANon-homologous end joining
- BNon-homologous editing joints
- CNon-heterodimeric end joints
5What are the requirements for NHEJ?
- ADouble strand breaks
- BSingle strand breaks
- CT-T lesions
- DDNA ligase 4
- EDNA ligase 2
6The repair process of NHEJ will join any 2 free ends together, regardless of homology
- AVerdadero
- BFalso
7An error in NHEJ can lead to translocation between which chromosomes, forming what type of chromosome fusion?

8The repair process of Homologous Recombination relies on what?

9What is required for an error in Homologous Recombination?
- AA faulty alignment of the two chromosomes
- BA faulty alignment of the two chromatids
- CDue to inversions
- DDue to translocations
- EDue to repeats
10What type of repair is the image showing?
