Lesson Objective

Explain how the sequence of nucleotides in mRNA determines the amino acid sequence of a polypeptide, and describe the steps of translation.

How do the structural features of a ribosome and tRNA ensure that the correct amino acid is matched to each mRNA codon?

Why does the universality of the genetic code across bacteria, plants, and animals serve as strong evidence for shared evolutionary ancestry?

6.4-Translation

Detailing the second half of the central dogma: converting an mRNA sequence into a physical polypeptide chain.
