Codons

What is a codon?

• It is a three letter section of bases that are read by ribosomes to stamp amino acids into a protein

• They are the codes on the DNA (hence "code-on"

• It is a type of mutation that occurs when there has been a substitution, deletion or insertion.

• It is a made up word for this quiz. Nice try, Wampler.

The "language" of mRNA is called the ​ (a)   , and it uses three-letter "words" called ​ (b)  

• genetic code

• codons

• nucleotide strategy

• anti-codons

• amino acids

Answer explanation

The 'language' of mRNA is referred to as the genetic code, and it uses three-letter 'words' called codons to encode specific amino acids during protein synthesis.
