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 |
2. structural genes
3. an enhancer
4. a promoter
DNA replication in bacteria occurs:
1. Within nucleolus
2. Prior to fission
3. Just before transcription
4. During S phase
2. lactose
3. lactose and galactose
4. glucose
Identify the correct order of organization of genetic material from largest to smallest.
1. Chromosome, gene, genome, nucleotide
2. Genome, chromosome, nucleotide, gene
3. Genome, chromosome, gene, nucleotide
4. Chromosome, genome, nucleotide, gene
Gene regulation governing lactose operon of E. coli that involves the lac I gene products is:
| 1. | positive and inducible because it can be induced by lactose. |
| 2. | negative and inducible because repress or protein prevents transcription. |
| 3. | negative and repressible because repress or protein prevents transcription. |
| 4. | feedback inhibition because excess of β galactosidase can switch off transcription. |
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 |
An analysis of chromosomal DNA using the Southern hybridization technique does not use:
1. Electrophoresis
2. Blotting
3. Autoradiography
4. PCR
