DNA of E. Coli:
1. ds circular
2. ss circular
3. ds Linear
4. ss Linear
Knife of DNA:
1. DNA–ligase
2. Restriction endonuclease
3. Exonuclease
4. Peptidase
Genetic engineering involves:
1. Use of restriction endonuclease on bacterial DNA and formation of new traits
2. Use of Ligase for cutting DNA
3. Developing instruments
4. Use of statistic in genetics
Which of the following is most used in genetic engineering:
1. E. coil and Agrobacterium
2. Mycobacteria and Salmonella
3. Aspergillus
4. Penicillium
Function of Nucleases:
1. | Break the polynucleotide chain by breaking each terminal nucleotide |
2. | Breaks phosphodiester bond |
3. | Breaks peptide bonds |
4. | Breaks ester bonds |
Hybridoma is:
1. | Collection of DNA from DNA |
2. | Collection of RNA from DNA |
3. | A fusion of tumour sex cell with non tumour sex cell |
4. | A fusion of tumour somatic cell with non tumour somatic cell |
The bacteria generally used for genetic engineering is:
1. Agrobacterium
2. Bacillus
3. Pseudomonas
4. Clostridium
A giant rat is formed in the laboratory, what is the reason:
1. Gene mutation
2. Gene synthesis
3. Gene manipulation
4. Gene replication
Plasmid has been used as a vector because:
1. | It is circular DNA that has the capacity to join to eukaryotic DNA |
2. | It can move between prokaryotic and eukaryotic cells |
3. | Both ends show replication |
4. | It has an antibiotic resistance gene |
What is true for a plasmid?
1. Plasmids are widely used in gene transfer
2. These are found in a virus
3. A plasmid contains genes for vital activities
4. This is the main part of the chromosome
