Statement I: | RNA mutates at a faster rate. |
Statement II: | Viruses having RNA genome and shorter life span mutate and evolve faster. |
1. | Statement I is false but Statement II is true. |
2. | Both Statement I and Statement II are true. |
3. | Both Statement I and Statement II are false. |
4. | Statement I is true but Statement II is false. |
Statement I: | RNA being unstable, it mutates at a faster rate |
Statement II: | RNA can directly code for synthesis of proteins hence can easily express the characters. |
Which one of the following is not a criterion of genetic material?
1. | Should not provide the scope for changes for evolution |
2. | Should be able to express itself in the form of Mendelian character |
3. | Should be able to generate its replica |
4. | Should be stable chemically and structurally |
