Question

If a Rotavirus, a dSRNA virus that causes gastroenteritis, infects little Peter that is 2 years old his immune system will be able to fight using a beta interferon cascade of events are the correct order:

Step 1 = ____________

Step 2 = ____________

Step 3 = ____________

1. Rotavirus buds off first cell
2. Transcription and translation of AVN proteins
3. Triggers transcription and translation of IFN
4. IFN binds to neighbor cells surface receptors
5. Virus enters the cell
6. AVN Proteins binds to rotavirus dsRNA

Answer 1

STEP 1: VIRUS ENTERS THE CELL. INTERFERON SECRETION IS BY THE CELL RESPONSE TO PRESENCE OF FOREIGN BODY OR VIRUS. STEP 2: TRIGGERS TRANSCRIPTION AND TRANSLATION OF IFN( INTERFERONE). - EARLY INNATE RESPONSE OF THE CELL TO VIRAL INFECTION IS THE SECRETION OF INTERFERONE. THEN IT UNDERGO RNA SYNTHESIS ( TRANSCRIPTION) AND MRNA PROTEIN SYNTHESIS ( TRANSLATION). STEP 3: IFN BINDS TO NEIGHBOR CELLS SURFACE RECEPTORSRECEPTORS- IT PLAY A MAIN ROLE IN CELL SIGNALING. OTHER OPTIONS ARE RELATED TO VIRAL REPLICATION PROCESS
