Question

The direction of synthesis of an RNA transcript is _____.

- 1' —> 5'
-5' —> 3'
-1' —> 3'
-3' —> 5'
-2' —> 4'

Answer 1

The direction of synthesis of an RNA transcript is from the 5' end to the 3' end.

Step-by-step explanation:

The direction of synthesis of an RNA transcript is 5' —> 3'.

During transcription, RNA polymerase reads the DNA template in a 3' to 5' direction and synthesizes the RNA molecule in a 5' to 3' direction. This means that the RNA polymerase moves along the DNA template from the 3' end to the 5' end.

For example, if the DNA template strand is 3'-CTAGGCTA-5', the synthesized RNA molecule will be 5'-GAUCCGAU-3'.
