Likewise, an artificial mRNA consisting of alternating A and C bases would code for alternating amino acids histidine and threonine. Gradually, a complete listing of the genetic code codons was developed. Image from W.H. Freeman and Sinauer Associates, used by permission. The genetic code consists of 61 amino-acid coding codons and three termination codons, which stop the process of translation. Image from W.H. Freeman and Sinauer Associates, used by permission.
Terminators are the stop signals.
The length of rRNA differs in each. The 30S unit has 16S rRNA and 21 different proteins. The 50S subunit consists of 5S and 23S rRNA and 34 different proteins. Image from W.H.
