A24-year-old g4p2 woman at 34 weeks gestation complains of a cough and whitish sputum for the last three days. she reports that everyone in the family has been sick. she reports a high fever last night up to 102°f (38.9°c). she denies chest pain. she has a history of asthma with no previous intubations. she uses an albuterol inhaler, although she has not used it this week. vital signs are: temperature 98.6°f (37°c); respiratory rate 16/minute; pulse 94 beats/minute; blood pressure 114/78; peak expiratory flow rate 430 l/min (baseline documented in the outpatient chart = 425 l/min). on physical examination, pharyngeal mucosa is erythematous and injected. lungs are clear to auscultation. white blood cell count 8,700 mcl; arterial blood gases on room air (normal ranges in parentheses): ph 7.44 (7.36–7.44); po2 103 mm hg (> 100); pco2 26 mm hg (28–32); hco3 19 mm hg (22–26). chest x-ray is normal. what is the correct interpretation of this arterial blood gas?

Poliovirus is an rna virus of the picornavirus group, which uses its rna as mrna. at its 5' end, the rna genome has a viral protein (vpg) instead of a cap. this is followed by anontranslated leader sequence, and then a single long protein-coding region (~7000 nucleotides), followed by a poly-a tail. observations were made that used radioactive amino acid analogues. short period use of the radioactive amino acids result in labeling of only very long proteins, while longer periods of labeling result in several different short polypeptides. what conclusion is most consistent with the results of the radioactive labeling experiment? a) host cell ribosomes only translate the viral code into short polypeptides.b) the rna is only translated into a single long polypeptide, which is then cleaved into shorter ones.c) the rna is translated into short polypeptides, which are subsequently assembled into large ones.d) the large radioactive polypeptides are coded by the host, whereas the short ones are coded for by the virus.
