Explain the nursing actions which are the basis for safe, competent nursing care and the underlying principles of each competency.

Some viruses can be crystallized and their structures analyzed. one such virus is yellow mottle virus, which infects beans. this virus has a single-stranded rna genome containing about 6300 nucleotides. its capsid is 25-30 nm in diameter and contains 180 identical capsomeres.if the yellow mottle virus begins its infection of a cell by using its genome as mrna, which of the following would you expect to be able to measure? a) replication rateb) transcription ratec) translation rated) formation of new transcription factors

Avirus consisting of a single strand of rna, which is transcribed into complementary dna, is a ) proteaseb) retrovirusc) rna replicase virusd) nonenveloped virus
