Review the Chapter Concepts list. These all center around how genetic information is stored in DNA and transferred to RNA prior to translation into proteins. Write a short essay that summarizes the key properties of the genetic code and the process by which RNA is transcribed on a DNA template.
Chapter Concepts
▪Genetic information is stored in DNA by means of a triplet code that is nearly universal to all living things on Earth.
▪The genetic code is initially transferred from DNA to RNA, in the process of transcription.
▪Once transferred to RNA, the genetic code exists as triplet codons, which are sets of three nucleotides in which each nucleotide is one of the four kinds of ribonucleotides composing RNA.
▪RNA's four ribonucleotides, analogous to an alphabet of four "letters," can be arranged into 64 different three-letter sequences. Most of the triplets in RNA encode one of the 20 amino acids present in proteins, which are the end products of most genes.
▪Several codons act as signals that initiate or terminate protein synthesis.
▪In eukaryotes, the process of transcription is similar to, but more complex than, that in prokaryotes and in the bacteriophages that infect them.
