Making Proteins from DNA
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.
Key Concepts
Proteins are long chains of amino acids that are coded for by DNA.
During transcription, RNA polymerase unwinds DNA and creates mRNA using complementary base pairing.
In translation, tRNA molecules bring specific amino acids to the ribosome, where they match with mRNA codons to form a polypeptide chain.
