A
- DNA restriction enzyme
- Sticky ends
- DNA ligase enzyme
- Recombinant DNA
- Vector
2
Q
What does the DNA restriction enzyme do?
A
It cuts specific genes from chromosomes. The same one is also used to cut open plasmids.
3
Q
What are sticky ends?
A
Each DNA restriction enzyme cuts at a specific sequence of bases, producing short single stranded sections called sticky ends.
4
Q
What does DNA ligase enzyme do?
A
It forms bonds between the nucleotides to stick both pieces of DNA together.
5
Q
What is recombinant DNA?
A
A combination of DNA from 2 different sources.
6
Q
What is a plasmid/ virus carrying the human DNA referred to as?
A
A vector - it can insert the recombinant DNA into other cells.
