At medicago, scientists remove a specific genetic sequence that codes for a hemagglutinin protein from an influenza virus and insert 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.

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 Agrobacterium 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.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
