Answer:
Type of nucleic acid.
Explanation:
Virus may be defined as the organism that can contains both DNA and RNA as their genetic material. Virus acts as non-living outside the host environment and later acts as living organism inside the host.
Some virus that particularly contain DNA as genetic material. Some virus has the ability to transform RNA into the DNA molecule. Some virus contains only RNA as their genetic material and DNA is not involved in their life cycle.
Thus, the correct answer is option (a).
Answer:
Complete dominance Result from successive mutations of the same GENE.
Explanation:
The 7 (sometimes 8) characteristics of life are:
1. living things are composed of cells
2. living things have different levels of organization
3. living things metabolize (i.e. use energy)
4. living things respond to their environment
5. living things grow
6. living things reproduce
7. living things adapt to their environment
(some sources include) 8. living things have genetic material
Viruses do not metabolize, they do not grow, they do not adapt to their environment, and they cannot reproduce independently; viruses require host cells to reproduce and perform the other functions that give them the appearance of aliveness.
