Do Bacteria Have Genetic Material? 9 Facts You should Know

WebMar 27, 2024 · Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing. The two main classes of nucleic acids are deoxyribonucleic acid ( DNA) and ribonucleic acid ( RNA ). DNA is the master blueprint for life and constitutes ... WebIn bacteria, RNA transcripts can act as messenger RNAs ( mRNAs) right away. In eukaryotes, the transcript of a protein-coding gene is called a pre-mRNA and must go through extra processing before it can direct translation. Eukaryotic pre-mRNAs must have their ends modified, by addition of a 5' cap (at the beginning) and 3' poly-A tail (at the end).
