In Neurospora, the mutant stp exhibits erratic stop-and start growth. When a female of stp strain is crossed with a normal strain acting as a male, all progeny individuals' showed stp mutant phenotype. However, the reciprocal cross resulted in all normal progeny, individuals. These results can be explained on the basis of

A. Uniparental gene contribution

B. Nuclear inheritance with concept of dominance

C. Sex link character

D. stp mutation may be located in chloroplast DNA

Particular receptor tyrosine kinases (RTKs) that promote excessive cell division are found at high levels in various cancer cells. HER2 is an RTK that is present at excessively high levels in some breast cancer cells. Herceptin is a protein that binds to HER2 and inhibits cell division. Herceptin may be an effective treatment for breast cancer treatment under which of the following conditions?
