Final answer:
The not true statement about coronaviruses is that they replicate through reverse transcription; they use RNA-dependent RNA polymerase. Also, German measles is not associated with coronaviruses, as it is caused by the rubella virus.
Step-by-step explanation:
The statement that is NOT true regarding coronaviruses is that SARS-CoV-2 replicates by reverse transcription inside the host cell. Coronaviruses, including SARS-CoV-2 - also commonly known as the coronavirus - are RNA viruses that replicate using RNA-dependent RNA polymerase, rather than through reverse transcription, which is a method used by retroviruses. The coronavirus uses its spike proteins to attach to the host cells and infect them, eventually leading to illnesses that can vary from mild to severe, such as the common cold, severe acute respiratory syndrome (SARS), and Middle East respiratory syndrome (MERS).
Additionally, German measles is not one of the diseases associated with coronavirus infections. German measles is caused by the rubella virus, which is distinct from coronaviruses.
By not killing the host cell immediately, the influenza virus, which uses a different method of replication than coronaviruses, can continue to replicate and spread without triggering immediate immune system responses that might contain the infection more swiftly.
