Document Summary
Dna as a blueprint and transcription in prokaryotes. The dna molecules found in prokaryotic and eukaryotic chromosomes are the same. The same basic subunits of adenine,thymine, cytosine and guanine nucleotides, are used to make up a dna sequence. The dna molecule is often described as the. This is because each dna molecule will often contain thousands of genes that code for proteins or rna molecules that have various functions in the cell. As a result, it is in the dna of a cell that information is stored. This stored information can be interpreted and transmitted for important cellular processes. Genes are sections of the dna molecule which contain information that is then transcribed into an rna copy. Genes present in a dna molecule are able to code for speci c proteins. This process of copying and interpreting genes into proteins is known as the central dogma.
