RNAmolekyylistä
RNAmolekyyli, or ribonucleic acid molecule, is a crucial type of nucleic acid that plays a central role in various biological processes, primarily related to the expression of genes. Unlike its double-stranded counterpart, DNA, RNA is typically a single-stranded molecule. Its structure consists of a chain of nucleotides, where each nucleotide is composed of a ribose sugar, a phosphate group, and one of four nitrogenous bases: adenine (A), guanine (G), cytosine (C), and uracil (U). Uracil replaces thymine, which is found in DNA.
The primary function of RNA is to act as an intermediary between DNA and protein synthesis. Messenger
Beyond its role in protein synthesis, RNA molecules also exhibit diverse regulatory and catalytic functions. Small
