AGGTATCGCAT is a sequence from the coding strand of a gene. What will be the corresponding sequence of the transcribed mRNA?
| 1. | AGGUAUCGCAU | 2. | UGGTUTCGCAT |
| 3. | ACCUAUGCGAU | 4. | UCCAUAGCGUA |
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
Which of the following statement is not correct?
| 1. | Satellite DNA normally do not code for any protein but they form a large portion of human genome. |
| 2. | Satellite DNA shows high degree of polymorphism and forms basis of DNA finger printing. |
| 3. | Satellite DNA is widely used as identification tool in forensic science. |
| 4. | Satellite DNA is not transmitted as mendelian trait from parent to progeny. |
Select the correct option:
