1. Two genetically identical copies of DNA
2. Finds an error in DNA, removes the incorrect nucleotide and replaces it with a correct one.
3. It is used as a copy/ "template" for replication in order to have two identical copies of DNA.
4. DNA helicase unwinds DNA double helix and Topiosomerase ensure there isn't too much unwinding.
5. Replication has a built on proofreading system - DNA polymerase removes the incorrect nucleotide and replaces it with a correct one.
I think the answer your looking 4 is B

Answer: C. M. rupestris, M. eastwoodiae, and M. nelsonii; they put more energy into making rooted branches than they put into making nectar and seeds.
Explanation:
In asexual mode of reproduction the plant does not produce gametes. The plant reproduce through vegetative propagation or spore formation. The plant does not produce nectar as no flowers are produced to attract the pollinators.
In sexual mode of reproduction the plant will develop the gametes and flowers will produce the nectar to attract the pollinators.
Thus on the basis of above explaination, C is the correct option. As the plants will invest more energy in making roots which are the organs for vegetative propagation a process of asexual reproduction.
The answer should be an unconformity
