WebThe DNA molecule consists of 4 nitrogen bases, namely adenine (A), thymine (T), cytosine (C) and Guanine (G), which ultimately form the structure of a nucleotide. The A and G are purines, and the C and T are pyrimidines. The two strands of DNA run in opposite directions. These strands are held together by the hydrogen bond that is present ...

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. WebEach strand of a DNA molecule contains nitrogenous bases that pair with other nitrogenous bases in very specific ways.
