If you're referring to stop codons, then there are three: UAA, UAG and UGA. They do indeed stop translation, though I wouldn't say they halt ribosomes. Stop codons code for a releaser enzyme, one that fits the A site of the ribosome, but does not carry an amino acid. This enzyme cuts the bond between the polypeptide and the last tRNA.

What determines where on the DNA molecule transcription begins and where it ends?
I think you are referring to translation - translation is the process of replicating the DNA sequence in order to produce a code for the production of a particular protein, known as an mRNA strand. This code is read in sequences of three bases known as codons. The beginning and end of the mRNA strand is determined by start and stop codons. Start codons, unlike stop codons, also need nearby sequences and initiation factors in order to begin translation. Start codons include base sequences of usually AUG or possibly GUG or UUG depending on the organism. There are three stop codons and these are UAG, UGA and UAA
What is the function of start codon?
The start and stop codons signify the start and end of a protein - they are important for ensuring that the correct protein length (and therefore protein structure) is created.
What is the third codon in the mrna you produce in?
What the third codon is differs depending on the type of mRNA used for translation. The one thing that all translations have in common is that they all start with methionine (AUG), the start codon, and end with one of several stop codons. Everything in between is determined by the mRNA.
The process of synthesizing proteins based on an mRNA template is called?
transformation
What halts translation in DNA?
In the translation of a DNA a stop Codon will help to put a stop to the process of translation.There are three stop codons used in the process when a ribosome reaches one of the Codon it stops.
How arrangement of codons in the genetic code minimize the impact of mutations?
Based on the DNA or RNA, based on the organism and based on the process of RNA and DNA the arrangement of codons will occur. During translation process in mRNA the tRNA's anticodon region comes and binds to the start codon ( AUG, GUG, UUG) of the mRNA where the translation process initiated and the process was and at the stop codon ( UAG, UAA, UGA) region the translation process was terminated. From organism to organism the arrangement of the codons will changed based on the number of basepairs.

What is the translational purpose?
Translation is the process of "reading" the bases of mRNA - in respect of Triplet-Codons - and converting these into the [amino acid] primary structure of a protein.
What is a true statement about codons?
In translation, an mRNA codon is recognized by its complementary tRNA. /\
In genetics what is translation and what does it produce?
In genetics, translation is the process in which the sequence of codons on a mRNA molecule are translated into a sequence of amino acids by tRNA, which results in a protein. This process occurs on ribosomes in the cytoplasm and the rough endoplasmic reticulum.
What process does transfer RNA participate in?
Transfer RNA (tRNA) participates in the process of translation. During translation, the tRNA molecules bring amino acids to the ribosome, matching them with the corresponding codons on the messenger RNA (mRNA) to form a polypeptide chain. This process allows for the synthesis of proteins based on the genetic information encoded in the mRNA.
What do you mean by stop codons?
a stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation.Three codons UAG,UAA & UGA are the stop codons, which denotes the end of the protien.
What is the function of start codon?
The start and stop codons signify the start and end of a protein - they are important for ensuring that the correct protein length (and therefore protein structure) is created.
What part do codons and anticodons play in translation?
tRNAanti-codonsact as the interpreters of the mRNA codon sequence

A codon is a triplet base sequence?
mRNA
Is transcription the final process in the assembly of a protein?
Transcription is the process in which an mRNA is synthesized beginning from a DNA template.Translation is the process of assembling a protein. The genetic information coded on the mRNA is essential in assembling a protein.During translation, the genetic information (read as triplet codons) on the mRNA is used as a template to construct a peptide one amino acid at a time.
