Consider the following statements :
I. No virus can survive in/ocean waters.
II. No virus can infect bacteria.
III. No virus can change the cellular transcriptional activity in host cells.
Which of the statements given above are correct?
Consider the following statements :
I. No virus can survive in/ocean waters.
II. No virus can infect bacteria.
III. No virus can change the cellular transcriptional activity in host cells.
Which of the statements given above are correct?
Statement I is not correct. Many viruses are found in ocean waters. Marine viruses, including bacteriophages and viruses infecting plankton, are abundant and play critical roles in oceanic ecosystems, including nutrient cycling and microbial regulation. Statement II is not correct. Viruses that infect bacteria are known as bacteriophages. These are extensively studied in microbiology and are used in biotechnology and phage therapy. Statement III is not correct. Viruses are known to alter the transcriptional activity of host cells. They hijack host cell machinery to replicate and often modify gene expression, leading to significant changes in cellular function.
