Learning Objective
I can describe the steps of protein synthesis, including transcription and translation. I can write the complementary mRNA sequence from a DNA sequence. I can use a codon wheel to determine the amino acid sequence from mRNA.
- 1
Proteins are long chains of amino acids that are coded for by DNA.
- 2
During transcription, RNA polymerase unwinds DNA and creates mRNA using complementary base pairing.
- 3
In translation, tRNA molecules bring specific amino acids to the ribosome, where they match with mRNA codons to form a polypeptide chain.
