Question

A segment of RNA has the sequence AUU. What explanation can be made about how this codon came to be?

A
The RNA strand formed from the rearrangement of the bases in a DNA strand.

B
The RNA strand broke off from a DNA strand that had a much longer genetic code.

C
The RNA codon was transcribed from a DNA strand with the sequence TAA.

D
The RNA codon was transcribed from a DNA strand that had the sequence UAA.

Answer 1

C - The RNA codon was transcribed from a DNA strand with the sequence TAA.

Step-by-step explanation:

transcription describes the process by which a strand of mRNA is coded for by the protein RNA polymerase taking RNA bases and matching them in complimentry with the DNA bases
