Every HIV particle contains two RNA molecules.If two genes from one RNA molecule become detached and then,as a unit,get attached to one end of the other RNA molecule within a single HIV particle,which of these is true?
A)There are now fewer genes within the viral particle.
B)There are now more genes within the viral particle.
C)A point substitution mutation has occurred in the retroviral genome.
D)One of the RNA molecules has experienced gene duplication as the result of translocation.

Quizplus · Accepted Answer

Gene duplication through translocation occurs when a segment of a gene detaches and then reattaches to a different location within the genome. In this scenario, the detachment of two genes from one RNA molecule and their attachment to the end of the other RNA molecule within the same HIV particle results in one of the RNA molecules having additional genetic material, hence a gene duplication event due to translocation. There is no increase or decrease in the total number of genes within the viral particle, nor is there a point substitution mutation, which would involve a change in a single nucleotide.
