Cancer Do mitochondrial genomes use the same stop codons as nuclear genomes?

3 stop codons indicate the end of the protein (UAG, UAA, UGA) and 1 start codon indicates the beginning of the protein (AUG). The code is degenerate = more ... Most codons specify an amino acid; Three "stop" codons mark the end of a protein; One "start" codon, AUG, marks the beginning of a protein and also encodes ... May 2, 2023 ... A stop codon is a trinucleotide sequence of three nucleotides found in messenger RNA (mRNA) or DNA that instructs the cell to stop production of ... Objectives: The HIV-1 nef gene terminates in a 3'-UGA stop codon, which is highly conserved in the main group of HIV-1 subtypes, along with a downstream ... Jul 29, 2011 ...
