Document Summary
The central dogma states that genes are expressed in the phenotype or morphology of an individual via protein action. The central dogma is split into two parts transcription and translation. The information to make a protein comes from a gene in the dna molecule referred to as. In order for one gene to direct the production of numerous essential proteins, copies of the. Every copy will eventually amount to a specific polypeptide sequence. Therefore, the central dogma is a sequence of events that begin with a genetic code and end with a protein. The template region of dna is first copied , or transcribed into an mrna, and then. Like dna, rna is a carrier of genetic information. Rna differs from dna in the following ways: Rna contains a ribose sugar, not a deoxyribose sugar. Rna is single-stranded, whereas dna is double-stranded instead of thymine, rna contains uracil , which is still able to pair up with adenine.
