PLEASE HELP ME ANSWER THIS Which of the following explains the role Chargaff's rule plays in transcription?

a. The RNA polymerase uses Chargaff's rules to create the random strand of RNA.

b. Transcription is the process of using Chargaff's rule to make DNA from scratch.

c. The RNA polymerase uses Chargaff's rules to create the complementary strand.

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
