Answer:
All of the choices are correct
Explanation:
The respiratory syncytial virus (RSV) is an enveloped, negative-strand RNA virus (Paramyxoviridae family) capable of infecting ciliated cells of the airways by using its surface glycoproteins G and F for attachment and fusion during viral entry in target cells. RSV can affect the lungs and parts of the respiratory system (e.g., nasopharynx). Although RSV generally causes mild, cold-like symptoms, this virus may also lead to severe infection in babies (12 months) and infants, being one of the most common types of respiratory infections in children, older adults, and immunocompromised patients. Some common symptoms in individuals with RSV pneumonia include fever, nonproductive cough, dyspnea, wheezes, rales, rhonchi, etc.
Answer: An inversion mutation is one type of mutation. Inversion mutations occur when a section of DNA breaks away from a chromosome during the reproductive process and then reattaches to the chromosome in reversed order.
Answer and Explanation:
Mitosis pursues an extremely exact procedure, yet cytokinesis doesn't as in that anything incorrectly occurs in the development of daughter nuclei in meiosis or mitosis the entire daughter cells may breakdown or dead or they will be imperfect in these two cases yet cytokinesis doesn't require exact system its alright if daughter cells are of various sizes or shape it won't influence result of cells.
Answer:
Option (2).
Explanation:
Ames test is used to identify the mutageneicity of the compound. The bacteria are treated with chemicals in the nutritive environment to determine whether the substance can acts as a mutagen or not.
The bacteria that can restore the biosyntheic activity in the environment can be considered as mutagen. The mutant bacteria can be easily identified in the Ames test.
Thus, the correct answer is option (2).
