RNA sequences are strands of ribonucleic acid that play a crucial role in the process of translating genetic information from DNA into proteins. These sequences are made up of nucleotides, which are the building blocks of RNA. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base. The order of these bases in an RNA sequence determines the specific instructions for protein synthesis. There are different types of RNA, including messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). mRNA carries the genetic code from DNA to the ribosomes, where proteins are assembled. tRNA helps in translating the mRNA sequence into a specific amino acid sequence, while rRNA forms the core of ribosome structure and function.
