Answer:
An amino acid can be encoded by more than one codon.
Explanation:
Codons are triplets of nucleotides in mRNA that are used for the protein synthesis (translation). A codon specifies a single amino acid, but there are exceptions. tRNA molecule contain anticodons, triplets of nucleotides that are complementary to codons. So, during the translation, tRNA carries the amino acid, that corresponds to the codon in mRNA.
Degenerate genetic code (more than one codon can code for the same amino acid) is important, because when point mutation occurs it is possible that the amino acid remains unchanged.
Answer:
Invasive species are among the leading threats to native wildlife. Approximately 42 percent of threatened or endangered species are at risk due to invasive species. These species were brout from other countries and they cause problems in these other countries or continents. Like the bees in america were not native and neither werer the cattle in the western hemisphere.
