1. | a nematode, Meloidogyne incognita. |
2. | a nematode, Caenorhabditis elegans. |
3. | a trematode, Clonorchis sinensis. |
4. | a cestode, Taenia sloium. |
RNAi, as a mechanism of cellular defense, takes place in:
1. | All bacteria | 2. | All unicellular organisms |
3. | All plants only | 4. | All eukaryotic organisms |
Antisense technology:
1. | selectively blocks the expression of a gene. |
2. | combines genetic material from different species. |
3. | combines organelles and cells. |
4. | alters or transfers cells. |
I: | An infection by viruses having RNA genomes |
II: | Mobile genetic elements that replicate via an RNA intermediate |
III: | Integration of phage DNA into the main chromosomal DNA of a eukaryotic cell |
1. | Only I and II | 2. | Only I and III |
3. | Only II and III | 4. | I, II and III |
Silencing of a gene could be achieved through the use of:
1. | RNAi only | 2. | antisense RNA only |
3. | both RNAi and antisense RNA | 4. | none of the above |
