RNApolynukleotidkjeder
RNApolynukleotidkjeder, commonly known as RNA polynucleotide chains, are essential macromolecules found in all living organisms. They are linear polymers composed of repeating nucleotide subunits. Each nucleotide in an RNA chain consists of three parts: a ribose sugar, a phosphate group, and a nitrogenous base. The four nitrogenous bases found in RNA are adenine (A), guanine (G), cytosine (C), and uracil (U). These bases pair specifically, with adenine always pairing with uracil, and guanine with cytosine, although uracil replaces thymine (T) which is found in DNA.
The sugar-phosphate backbone of an RNA polynucleotide chain is formed by phosphodiester bonds linking the phosphate
RNA polynucleotide chains play diverse and crucial roles in cellular processes. Messenger RNA (mRNA) carries genetic
