1. Precise words:Find the nonspecific terms in the following sentences. Replace the nonspecific choices with more preciseterms or phrases (It is not necessary to change the sentence structure).(i) All OVE mutants showed enhanced iP concentrations.(ii) Plants were kept in the cold overnight.(iii) To provide proof of concept for our hypothesis, we studied a virus in its host cell.(iv) The present paper reports on continuing experiments that were performed to clarify thissurprising effect.(v) The first transition state is a little lower in energy than the second transition state.

Q6. The bacterium Rhizobium radiobacter is well known to biologists because it has the rather astonishing ability to cause natural genetic engineering. That is, several genes are moved from the bacterial cells directly into the nucleus of cells of many higher plant species. Expression of these transferred genes in the infected plants stimulates cell division, creating a mass of undifferentiated tissue.
Which of the following signals on these transferred genes could be recognized in the plant host cell but not in the original Rhizobium cell?
“TATA” box
transcription terminator hairpin loop
intron splice signals
SD box
A. 1, 2 and 3
B. 1 and 3
C. 2 and 4
D. 4 only
E. All of 1, 2, 3 and 4
Experiment:
In this activity yo Page 5
ze the results of experiments that investigate nutritional requirement of
several mutant strains of yeast. The mutations in these strains cause a nutritional requirement for an
amino acid, such that the strains will not grow in media that lack one specific amino acid. Any mutant
that has a nutritional requirement is called an auxotroph, and is incapable of growing in a "minimal
medium" containing only a carbon source (e.g., glucose), a simple nitrogen source (e.g., ammonium
sulfate), and various salts and minerals. Such strains can be supported on a medium supplemented
with only the missing nutrient or on a "rich" medium that contains amino acids, vitamins, nitrogenous
bases, etc. (often in the form of an extract from yeast). The wild-type individual that can synthesize
the metabolic component is a prototroph, and is capable of growth on minimal medium.
The mutant strains in this activity are unable to synthesize tryptophan, lysine, or histidine;…

- Plant viruses are known to be transmitted horizontally and vertically. Vertical transmission is transmission of a virus from a parent plant to its progeny, and horizontal transmission is one plant spreading the virus to another plant the spread of viruses from trees and tall plants to bushes and other smaller plants, and horizontal transmission is the spread of viruses among plants of similar size the transfer of DNA from a plant of one species to a plant of a different species, and horizontal transmission is the spread of viruses among plants of the same species the spread of viruses from upper leaves to lower leaves of the plant, and horizontal transmission is the spread of a virus among leaves at the same general levelarrow_forwardexplain what scaffold hopping is and why it is useful for drug development?arrow_forwardExplain the reason why these viruses encode their own special fusion protein rather than making use of a cell's SNARES.arrow_forward
