Answer:
They are more expensive than potatoes without the vaccine.
The genetically modified crops are produced by using the scientific procedures of genetic engineering. It involves the manipulation of the genome of these crops so as to make them disease resistant, improving the quality of the edible parts and increasing the yield of the plants. The crops are genetically modified with accuracy, precision and implementation of the technology therefore, the crops produced are expensive then the crops produce by the conventional method.
Hence, they are more expensive than potatoes without the vaccine is a disadvantage of the genetically engineered potato plants to produce potatoes that contain edible vaccines.
Explanation:
Answer:
The correct answer is- C. double or single-stranded DNA or double or single-stranded RNA.
Explanation:
All the viruses are intracellular parasites which means they obtain their nutrition from their host. Viruses do not have cellular level of organization. They only have their nucleic acid which is surrounded by a protein coat called a capsid.
The nucleic acid in viruses can be of different types. It can be single or double-stranded DNA or single or double-stranded RNA. Their genome can be linear or circular. They inject their genetic material in their host and introduce it in the host genome. Therefore the correct answer is C.
Answer:
A bacteriophage is a type of virus that attacks bacteria. In the lytic cycle, the virus hijacks the cell machinery of the bacterium that it has infected. In the lysogenic cycle, the viral DNA is incorporated into the bacterial DNA.
Explanation:
Its a type of virus.
