Question

What is a "Codon" in Biology?

Answer 1

Codons are series of 3 nucleotides in mRNA that usually code for a specific tRNA.  The tRNA (transfer RNA) TRANSFERS a particular amino acid to the codon to be added to the growing polypeptide chain (protein) that is being made by translation.  Codons can also be "stop codons" which tell the ribosome to stop making the protein strand.

Answer 2

lmao!!i'm just laerning about this too! a codon 'consists of 3 consecutive nucleotides that specify a single amino acid that is to be dd to the polypeptide'

i got this from the text book....my definition is a set of 3 bases in mRNA that is used to form a polypeptide/protien.

hope i helped xD

Answer 3

Our DNA is made up of long strands of 4 nucleotide bases that are abbreviated A, G, C, & T. A codon is three of these bases and each triplet encodes one of the amino acids.

A strand of DNA attagc/atg/ggcatgctaccgtatgctag....etc

The strand must be read in three base increments beginning with a start codon atg that begins an open reading frame that encodes a gene. This is how the transcription is begun in the correct registration to produce the mRNA.

This mRNA is then translated into a protein. Every three bases are read and translated to one amino acid from this template.
