10. An infectious agent composed of only protein

  1. Prions
  2. Virus

Answer: (1) Prions

-> Prion: a misfolded protein that can trigger normal proteins to fold abnormally. Prions are encoded by host chromosomes. Most common prion disease in humans is Creutzfeldt-Jakob disease (CJD).
-> Virions: a complete virus particle that includes genetic materials either RNA or DNA, protein coat (capsids), envelope, and protein materials. These are functional extracellular infectious forms of a virus that infect living tissues.
-> Viroids: infectious agents with naked RNA and without any protective layer such as a protein coat. They only infect plants and replicate by RNA-RNA transcription and lack protein-coding.
-> Virusoids: linear or circular RNA as genetic material that can’t be replicated autonomously. For replication, they require virus-infected cells that function as helpers in their replication.
-> Prions: misfolded protein having infectious nature. Prions are encoded by host.

13. Coronal suture completely fuses by the age of

  1. 40 yrs
  2. 30 yrs

Answer: (4) 45 yrs

-> Most successful estimate of age is done from sagittal suture, followed by lambdoid and then coronal.
-> The sutures start closing on the inner side at about 25 years of age.
-> On the outer side, posterior one-third of sagittal suture closes= about 30–40 years
-> Anterior one-third of sagittal + lower half of coronal= about 40–50 years
-> Middle of sagittal + upper half of coronal= about 50–60 years.
