Web25 de fev. de 2024 · Four 5’ nucleotides (G2 through to C5) form the P1 stem, a duplex that forms a minor groove triplex with the five-adenine (A 5) strand. This then passes into the 2N 4 region (so called because it contains two tetra-nucleobase interactions; G6 to U8) comprising a number of multiple-base interactions discussed below. WebBoth deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts: Purines and pyrimidines are the two categories of nitrogenous bases. Adenine and guanine are purines. Cytosine, thymine, and uracil are pyrimidines. …

WebTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination.
