Does a codon have three nucleotides and amino acid at the end?

Question

Does a codon have three nucleotides and amino acid at the end?

Answer 1

OK.  You're on the right track.  A codon is a sequence of three nucleotides and codes for an amino acid.  When a ribosome is 'scanning' along an mRNA transcript it reads it as individual codons.  Each codon (nucleotide triplicate) encodes an amino acid.  A tRNA anticodon interacts with the ribosome, binds its complementary codon, and adds a corresponding amino acid to the growing polypeptide chain.

So, does a codon have three nucleotides?  YES

An amino acid at the end?  Not really -- a codon purely describes what amino acid will be added to a growing polypeptide by a tRNA (transfer).

Good luck,

Answer 2

A codon is a set of 3 nucleotides that specify a specific amino acid. The codon is often referred to at the DNA level, however technically it has no meaning until mature  mRNA. The codon is "read" at the ribosome, and the matching tRNA carries the amino acid.

Answer 3

a codon is merely a sequence of three nucleotide bases in mRNA that carry the code for a particular amino acid. As there are 4 bases that can be ararnged in triplets this means there are 63 ( 4^3 ) possible combinations of three bases. There are 20 common amino acids so some amino acids have more than one code. BUT each three base code can only code for a particular amino acid

Answer 4

amino acids r buildin blocks of protein n they r 20 in number. they r differently coded in triple way

Answer 5

A codon is 3 nucleotides that encode an amino acid.
