Question
The first codon of an Open Reading Frame (coding region) is:Group of answer choices5' AUG 3' if you look at the tRNA5' CAT 3' on the coding strand5' AUG 3' on the mRNA5' ATG 3' on the template strand
Solution
The first codon of an Open Reading Frame (coding region) is 5' AUG 3' on the mRNA.
Here's why:
-
The process of protein synthesis begins with the transcription of DNA into mRNA.
-
In this process, the DNA strand that serves as a template is read in the 3' to 5' direction.
-
The mRNA is synthesized in the 5' to 3' direction.
-
The codon AUG is the start codon for protein synthesis.
-
Therefore, the first codon of an Open Reading Frame (coding region) is 5' AUG 3' on the mRNA.
