Answer:
The definitions in the attachment is numbered accordingly as follows:
1. Electrophoresis
2. Polymerase Chain reaction
3. DNA probe
4. Chromosome
5. Restriction enzyme
Explanation:
1. Gel electrophoresis is a biological technique used to separate DNA fragments according to their size and charge using electric current passed through a gel matrix containing the samples.
2. Polymerase chain reaction, commonly known as PCR, is a molecular technique developed by Kary Mullis. It is used to make million copies i.e. amplify of a specific segment of DNA from a very small amount of DNA.
3. DNA probe
