Webb18 dec. 2024 · RNA is a polymer consisting of chains of nucleotides. These are nitrogenous bases attached to phosphate groups and ribose sugars. The four bases in RNA are adenine, uracil, cytosine and guanine. RNA can form into double-stranded structures, such as during translation, when mRNA and tRNA molecules pair. Ribosomal ribonucleic acid (rRNA) is a type of non-coding RNA which is the primary component of ribosomes, essential to all cells. rRNA is a ribozyme which carries out protein synthesis in ribosomes. Ribosomal RNA is transcribed from ribosomal DNA (rDNA) and then bound to ribosomal proteins to form small and … Visa mer Although the primary structure of rRNA sequences can vary across organisms, base-pairing within these sequences commonly forms stem-loop configurations. The length and position of these rRNA stem-loops allow … Visa mer Both prokaryotic and eukaryotic ribosomes can be broken down into two subunits, one large and one small.

WebbLike DNA, RNA is made up of nucleotide consisting of a 5-carbon sugar ribose, a phosphate group, and a nitrogenous base. However, there are three main differences between DNA and RNA: RNA uses the sugar ribose instead of deoxyribose. RNA is generally single-stranded instead of double-stranded. RNA contains uracil in place of thymine.
