1.   List below all probable transfers proposed by Dr. Crick. (1 point)

2.   List below all possible transfers proposed by Dr. Crick. (1 point)

3.   List below all impossible transfers proposed by Dr. crick. (1 point)

4.   The basis of Dr. Crick’s 1970 paper was to clarify the central dogma of molecular biology in response to the “Central Dogma Reversed” publication. According to Dr. Crick, the work of Dr. Howard Temin suggests what? (1 point)

Explanation / Answer

1.theory proposed by him is known as central dogma and suggest flow of information nucleic acid to nucleic acid ,nucleic acid to protein.

2. Possible flow of information is flow of information from DNA to DNA through replication ,DNA to mRNA through replication ,mRNA to protein through translation and last one is mRNA to DNA through reverse transcription .

3 transfer of information from protein to protein or protein to nucleic acid is impossible .
