Biology Question on biotechnology
Discuss with your teacher and find out how to distinguish between
- Plasmid DNA and chromosomal DNA
- RNA and DNA
- Exonuclease and Endonuclease
Answer
a. Plasmid DNA and chromosomal DNA
| Plasmid DNA | Chromosomal DNA |
|---|---|
| Plasmid DNA is an extra-chromosomal DNA molecule in bacteria that is capable of replicating, independent of chromosomal DNA | Chromosomal DNA is the entire DNA of an organism present inside chromosomes |
b. RNA and DNA
| RNA | DNA |
|---|---|
| 1. | . RNA is a single stranded molecule |
| 2. | It contains ribose sugar. |
| 3. | The pyrimidines in RNA are adenine and uracil. |
| 4. | RNA cannot replicate itself. |
| 5. | It is a component of the ribosomes. |
c. ) Exonuclease and Endonuclease
| Exonuclease | Endonuclease |
|---|---|
| It is a type of restriction enzyme that removes the nucleotide from 5' or 3' ends of the DNA molecule. | It is a type of restriction enzyme that makes a cut within the DNA at a specific site to generate sticky ends |
