Synthesis of MRNAs in Paramyxoviruses Occurs Through a Single-Entry Mechanism

Multiple Choice

Synthesis of mRNAs in paramyxoviruses occurs through a single-entry mechanism, which is where the RNA-dependent RNA polymerase can only start transcription from the 3' end of the genome.Which of the following is a consequence of this mechanism?

A) More negative-strand genomes are produced than positive-strand antigenomes.
B) The RNA-dependent RNA polymerase binds to both end of the genome for genome replication
C) The RNA-dependent RNA polymerase binds to both ends of the genome for transcription
D) More mRNA is produced from the coding regions at the 5' end of the genome.
E) More mRNA is produced from the coding regions at the 3' end of the genome.
