At Medicago, scientists remove a specific genetic sequence that codes for a hemagglutinin protein from an influenza virus and in

sert this gene into an Agrobacterium genome. After the hemagglutinin gene is inserted into Agrobacterium, tobacco plants are infected with the Agrobacterium and the hemagglutinin gene is transferred into the tobacco plants. Which of the following allows the tobacco plants to express the hemagglutinin gene and produce the hemagglutinin protein?
Choose one or more:
A. the presence of a complete influenza virus genome in the tobacco plants.
B. a universal genetic code.
C. All living organisms produce at least low levels of the hemagglutinin protein.
D. promoters that allow the tobacco plants' RNA polymerase to recognize the gene.

Answer:

The correct answer will be options-B and D

Explanation:

The studies on the history of origin and evolution of life on Earth shows that all the organisms have evolved from a common descendant. This indicates that they possessed the same chemical-genetic or heredity molecule called Nucleic acid whether DNA or RNA.

DNA acts as the universal genetic material as it is present in all organisms except few. The process related to the DNA molecule is the same in all the organisms.

Since in the given question, the transfer of genes to plants via <em>Agrobacterium</em> and then the expression of the gene in plants shows that the passing of DNA has no barrier as  DNA is the genetic material and the enzyme RNA polymerase recognized the gene which could help produce the mRNA from the gene.

Thus, options-B and D is the correct answer.

(a) In human populations where HIV infection is common, are the frequencies of these "resistance genes" increasing, decreasing,
Misha Larkins [42]

Answer:

Increasing

Explanation:

This particular question or problem can be likened to a deductive reasoning. The viral disease known as HIV stand for Human Immunodeficiency Virus which is a disease that damages the immune system of anyone affected with the disease. The Human Immunodeficiency Virus goes through four main stages or steps that is to say the infection stage/step, the stages in which the symptoms does not show, the stages at which the symptoms start to show and the stage at which the Human Immunodeficiency Virus goes or turns to AIDS.

The frequencies of these "resistance genes" In human populations where HIV infection is common will increase. When Human Immunodeficiency Virus infection is common, people in  that particular society will develop more resistance to the virus and the survival of the fittest is taken into account as people with more resistance tends to be more healthier than the ones with less resistance.
