Question

Process of reverse transcription was discovered by
A. GarrodTemin and Baltimore
B. Beadle and Tatum
C. Marshall and Nirenberg
D. Holley and Grover

Answer 1

Hint: Reverse transcriptase is a process in which the central dogma of DNA processing forms double-stranded DNA from the RNA template which serves as a messenger. It was firstly discovered in retrovirus RNA. The discoveries independently isolated the RNA from two RNA tumour viruses. Their discoveries became the base for the HIV (AIDS) treatment and cancerous treating medicines.

Complete answer:
Rna transcription is the major important process essential for protein translation and uncoding the opposite or alternative coding on the lagging strand, it is also the basis for DNA genes to express itself.
It was first discovered by Howard Temin, he discovered the RNA and RNA transcription process in Rous sarcoma virions.
Independently Baltimore isolated the RNA from two tumour viruses.
These two tumour viruses are known to be murine leukaemia virus and another is Rous sarcoma virus.
Reverse transcriptase performs a work of enzyme which is used to produce DNA or say complementary DNA from an RNA template.
Without reverse transcriptase, it is not possible to incorporate in the host genome by the viral genome
Temin scientific fields and speciality was in the field of virology and genetics.
Baltimore major contributions were in immunology, virology, cancer research, biotechnology. He was a diverse specialist researcher in the scientific field who works on genetics, medicines and various other treatments.

The correct option is B) Temin and Baltimore.

Note:
Well developed studies on reverse transcriptase were studied on human immunodeficiency virus, murine leukaemia virus, telomerase reverse transcriptase occurring in eukaryotic chromosomes. Temin and Baltimore shared a Nobel prize in medicine which was concerned on the interacting between tumor viruses and the genetic material of the cell in the biomedical field of discoveries.
