The right answer is C) vector
In molecular biology and genetic engineering, vectors are DNA molecules that allow the propagation of sequences of interest. These are chimeric DNA molecules such as plasmids or artificial bacterial chromosomes, containing an origin of replication and one or more genetic markers. The origin of replication allows the maintenance of the vector in the target cell during generations.
Answer:
Purple colour arises due to the dominant alleles whereas white colour arises due to the recessive alleles.
For the purple colour to arise, even one of the dominant allele will be enough to cause the effect. On the other hand to see the recessive white trait, both the alleles of the gene should be recessive.
To ensure that only white flowers are grown, the farmers need to cross both white flowered plants to get the desired result.
Similar: They are made by proteins and glycoproteins like all the cells are. The also have DNA or RNA to reproduce and they also evolve to adapt.
Difference: They don't use the cell division phase and they are not alive.
Answer:
Meteorologists forecast tornadoes through the measurement of temperature, air speed and pressure conditions to monitor atmospheric conditions
Answer:
Herbaceous stems lack woody tissue and growth rings unlike woody xylem. Wood is a composite of cellulose fibers which require the the process of phloem in the bark to contain nutrients unlike herbaceous stems that rely on xylem that contains vessel and vascular elements.
