Answer #1

Ans:

B. non-segmented, negative (-) strand RNA.

Explanation: Rabies virus is a type of animal virus that causes rabies in human and animal. The genome contain a single negative (-) strand of genomic DNA whose sequence is complementary to that of the viral mRNA and it is non-segmented ( the genome is all on one single piece of RNA. The genomic RNA act as an template for synthesis of mRNA but doesn't itself encode protein. The rabies virus genome is not positive stranded because it doesn't contain same sequence as that present in mRNA. The genome doesn't the segmented fragment of RNA. Rabies virus genome doesn't contain double stranded DNA.

For the purposes of this problem we will ignore the fact that viral genomes can also be segmented or nonsegmented.You will need to do some outside research and examine the functional differences between two types of enzymes: exonucleases and endonucleases. Suppose four viral genomes were examined in the laboratory. The following information was obtained for each viral genome: Genome of virus 1: A = 28%, C= 22%, G = 24%, T = 0%, U = 26%, resistant to exonucleases but...
