Which one of the following is not applicable to RNA?
1. Complementary base pairing
2. 5' phosphoryl and 3' hydroxyl ends

Satellite DNA is important because it:
1. | Codes for proteins are needed in the cell cycle. |
2. | Shows a high degree of polymorphism in the population and also the same degree of polymorphism in an individual which is inheritable from parents to children. |
3. | Does not code for proteins and is the same in all members of the population. |
4. | Codes for enzymes needed for DNA replication. |
Which one of the following is wrongly matched?
1. | Transcription- Writing information from DNA to t-RNA |
2. | Translation- Using the information in m-RNA to make protein |
3. | Repressor protein- Binds to an operator to stop enzyme synthesis |
4. | Operon- Structural genes, operator, and promoter |
Transformation was discovered by:
1. Meseson and Stahl
2. Hershey and Chase
3. Griffith
4. Waston and crick
