(Q032) Which of the following statements about conditional alleles is FALSE? O Conditional alleles are only defective under high temperature conditions. O Conditional alleles can be used to study tissue-specific gene function in diploid organisms. Conditional alleles behave like the wild-type allele under permissive conditions. Conditional alleles allow for the study of lethal mutations in haploid organisms.

Respiratory Infections

Respiratory infections are infectious diseases of the respiratory tract that are mostly caused by bacteria and viruses. They cause infections of the throat, sinuses, airway path, and lungs. Respiratory infections are typically divided into two types: upper tract respiratory infection and lower tract respiratory infection.
