   2 days ago · RNA, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides and the nitrogenous bases adenine, guanine, cytosine, and uracil. Learn about the structure, types, and functions of RNA.

   Nucleic acids, macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in living organisms, all the way from single-celled bacteria to multicellular mammals like you and me.

   Oct 31, 2023 · The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is found in the nucleus of eukaryotes and in the chloroplasts and mitochondria.

   A gene is composed of DNA that is “read” or transcribed to produce an RNA molecule during the process of transcription. One major type of RNA molecule, called messenger RNA (mRNA), provides the information for the ribosome to catalyze protein synthesis in a process called translation.

   Nucleic acids are the building blocks of DNA and RNA. DNA stores and expresses genetic and hereditary information, while RNA is used to move the information around through transcription and translation to create proteins to work for the cell.

   • No, nucleoside is the combination of sugar and base. (when you remove phosphate from nucleoTide).
   • Don't fret! What do you want to start with first? We'll go as slowly as you need.
   • A macromolecule is a molecule containing a very large amount of atoms, such as a protein, nucleic acid, or synthetic polymer.
   • In the five carbon sugar of Deoxyadenosine Monophosphate, it is missing a oxygen atom while the Adenosine Monophosphate has the "missing" oxygen atom.

   To have a structural piece of DNA or RNA the nucleotides consist of a nucleic acid (differing Uracil in RNA from Thymine in DNA) a deoxygenized sugar (DNA) or oxygenized sugar (RNA) and a monophosphate (PO4) The bases are the 3 structures (nucleic acid, ribose and phosphate) bond together with a strong bond called a phosphodiester bond.
