Document Summary
The nucleotide contains a sugar, phosphate and nitrogenous base. Other similarities = both are nucleic acids, both are polynucleotides (made of many nucleotides), both are found in the nucleus of a cell. Transcription and translation help the flow of information of genetic information in a eukaryotic cell from dna to rna to protein. Transcription is the process of producing the copy of the required gene (think the way a transcript of a speech is written of the oral presentation). Transcription produces a transcript of the dna nucleotides. Then, translation decodes the copied rna sequence and produces the protein that it codes. Gene expression involves turning a gene on that includes the processes of transcription and translation (pp. Gene expression can be regulated by (a) repression or (b) activation. When the cell requires protein, the rna polymerase enzyme attaches to the promoter for the gene and transcribes it. The prokaryotic and eukaryotic cells regulate gene expression by regulating transcription.
