Question

Transducing viruses are caused by ________ in the provirus?

1) Inversion
2) Frameshift
3) Deletion
4) Mismatch

Answer 1

Transducing viruses are caused by insertion in the provirus, resulting in a frameshift mutation.

Step-by-step explanation:

Transducing viruses are caused by insertion in the provirus. This type of mutation is known as a frameshift mutation, which occurs when one or more nucleotides are inserted or deleted in the DNA sequence. In the case of transducing viruses, the provirus undergoes reverse transcription to form dsDNA, which is then integrated into the host genome. If an insertion occurs during this process, it can disrupt the reading frame of the genetic code, resulting in a frameshift mutation.
