One can argue that although the existence of retroviruses represents a complication of Crick's central dogma, it does not contradict it.The replication mechanism of retroviruses does not contradict the essence of the central dogma, because
A) retroviruses convert DNA information into RNA information.
B) retroviruses convert RNA information into RNA information.
C) even in retroviruses, information in proteins is not converted into DNA information.
D) even in retroviruses, DNA information is not converted into protein information.
E) retroviruses do not use tRNA.

Retroviruses do not contradict the central dogma because they still maintain the flow of information from DNA to protein without converting protein information into DNA information. Although retroviruses use RNA as their genetic material, the RNA is reverse-transcribed into DNA, which is then integrated into the host cell's genome. From there, the viral DNA is transcribed into RNA and eventually translated into protein. However, the viral proteins may also be involved in reverse transcription, which is a unique aspect of retroviral replication. Overall, the central dogma remains intact, but retroviruses provide an interesting exception to the typical flow of genetic information.
