RNA Types and Structure via an enzyme called RNA RNA A polynucleotide consisting essentially of chains with a repeating backbone of phosphate and ribose units to which nitrogenous bases are attached. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(a) tail. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. DNA Types and Structure is used as a template to make mRNA mRNA RNA sequences that serve as templates for protein synthesis. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine). Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. Stages of Transcription is the process by which DNA DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. This process is divided into 3 stages: initiation, elongation, and termination. Transcription is the process by which DNA is used as a template to make mRNA. Transcription Transcription Transcription of genetic information is the first step in gene expression.
