What you’ll learn

  1. ReadUse an RNA codon chart without losing the reading frame.Read mRNA in the 5-prime-to-3-prime direction, locate the start, group bases in threes, trace each codon through the chart, and stop at a termination signal.

Questions this course answers

What sets the reading frame in a standard translation example?

AUG initiates translation and establishes the triplet grouping that follows.

Which codon signals the end of translation?

UAG is one of the three standard stop codons.

What should you do with a DNA template strand before using an RNA codon chart?

The chart is for RNA codons, so a template strand must first be transcribed into complementary RNA.
