RNA

• ribonucleic acid copies the nucleotide sequence of DNA
• phosphate group and a five carbon sugar called ribose.
• 4 nitrogenous bases of RNA is cytosine guanine adenine uracil
• Messenger RNA acts as the messenger that copies the nucleotide sequence of the DNa inside the nucleus and carries it ou to the cytoplasm
• Ribosomal RNA is the site where the proteins are assembled
• Transfer RNA carries amino acid and transfer them to the ribosome
• Transcription happens when the mRNA enters the nucleus and copies the nucleotide sequence
• RNA polymerase attaches to one part of the DNA where the promoter is located
• Terminator indicates the end part of the DNa to be copied
• Translation happens when the nucleotide sequence carried by the mRNA will be used in the process.
• peptidyl tRNA binding site (p site) where the tRNA of a growing chain of amino acid or polypeptide chain is located.
• aminoacyl tRNA binding site holds the RNA that carries next amino acid.
• exit site serves as the holding place for the discharged tRNA
• anticodon made up of an amino acid and three nitrogenous bases
• codon is a set of three nitrogenous bases in the mRNA
• stop codon (UAA, UAG, UGA)
