Aug 18, 2020 · DNA and RNA are made up of monomers known as nucleotides. The nucleotides combine with each other to form a polynucleotide, DNA or RNA. Each nucleotide is made up of three components: a nitrogenous base, a pentose (five-carbon) sugar, and a phosphate group (Figure 1.1. 1). Harlequin opal for sale
The nuclear envelope isolates and protects a cell's DNA from various molecules that could accidentally damage its structure or interfere with its processing. During processing, DNA is transcribed , or copied into a special RNA , called messenger RNA (mRNA).

RNA structure The Structure of tRNA. The role of tRNA is two fold, bind to and accept the correct amino acid from the appropriate tRNA synthetase and recognize and bind the ribosome-mRNA complex to deliver the amino acid to the growing polypeptide chain. Because of its central role in gene expression (and its relative abundance), tRNA is one

🧬 Structure of DNA and RNA DNA and RNA are key carriers of biological information. For example, DNA may store a gene coding for haemoglobin or insulin , which is then processed by RNA and ribosomes (which are sophisticated machines themselves made of RNA and proteins) to manufacture those proteins.

Although DNA and RNA molecules possess very distinct biological functions, chemically RNA differs from DNA only in two aspects: (a) the absence of a methyl group at position 5 of the uridine (U), and (b) the presence of a 20-hydroxyl group of the RNA ribose sugar (Figure 1).
