How do bacterial species build antibiotic resistance

Biology
1 answer:
Minchanka [31]4 years ago

Antibiotic use promotes development of antibiotic-resistant bacteria. Every time a person takes antibiotics, sensitive bacteria are killed, but resistant germs may be left to grow and multiply. Repeated and improper uses of antibiotics are primary causes of the increase in drug-resistant bacteria.

Describe: UAG (as well as UAA and UGA) is an example of a stop codon. Molecules called release factors bind to stop codons. Plac
Marianna [84]

Answer and Explanation:

UGA, UAG and UAA are the stop codons in the genetic code. During translation, these stop codons signal the end of the polypeptide chain. These codons do not code for an amino acid. Therefore they are called termination codons or nonsense codons. These stop codons have been called as ochre (UAA), amber (UAG) and umber or opal (UGA). Richard Epstein and Charles Steinberg revealed Amber (UAG). They named it amber while remaining two stop codons named as ochre (UAA) and opal (UAG) to maintain the theme of ‘colors names’. Stop codons release the new polypeptide chain from the ribosome, during protein synthesis. This happens because there are no tRNAs with anticodon corresponding to the stop codon.
