Q. No.For the multiplication of any alien piece of DNA in an organism, it needs to be part of a chromosome that has a specific:
1.
Telomeric sequence
2.
Multiple cloning sites
3.
Ori
4.
Selectable marker
The first type II restriction endonuclease whose functioning depended on a specific DNA nucleotide sequence was:
| 1. | EcoRI | 2. | HindII |
| 3. | SmaI | 4. | BamHI |
The following palindrome is recognized by the restriction enzyme:
| 1. | BamHI | 2. | EcoRI |
| 3. | HindII | 4. | PstI |
A method used only for transforming animal cells is:
| 1. | Biolistics | 2. | Microinjection |
| 3. | Use of virus | 4. | Agrobacterium mediation |
Lysozyme should be used when isolating DNA in a pure form from:
| 1. | A bacterial cell | 2. | A fungal cell |
| 3. | A plant cell | 4. | An animal cell |
In recombinant DNA experiments, a vector:
| 1. | carries DNA into a new cell |
| 2. | links together newly joined fragments of DN |
| 3. | makes millions of copies of a specific segment of DNA |
| 4. | separates fragments of DNA by their length and electrical charges |
If any protein-encoding gene is expressed in a heterologous host, the protein formed is called:
| 1. | Recombinant protein | 2. | Native protein |
| 3. | Pro-protein | 4. | Exotic protein |
Gene cloning occurs:
| 1. | when a phage transfers bacterial DNA from one bacterium to another. |
| 2. | when a bacterium takes up DNA from the surrounding fluid. |
| 3. | when a bacterium carrying a recombinant plasmid reproduces, thus allowing for the production of multiple copies of the recombinant plasmid. |
| 4. | when DNA is produced from an RNA template. |
