Why must stop codons be present on DNA molecules?
stop codons signify the end of a polypeptide. They're like a period at the end of a sentance.
What molecule contains all of the codons needed to produce a particular polypeptide?
A single mRNA molecule has 3 codons i.e. 1 amino acid. The question is flawed and does not make sense!
What translates the mRna codons to amino acids?
The process of translating mRNA codons into amino acids is carried out by ribosomes in the cell. Transfer RNA (tRNA) molecules bring specific amino acids to the ribosome based on the codons in the mRNA. The ribosome then catalyzes the formation of peptide bonds between the amino acids, forming a polypeptide chain.
What do we call a codon that signals the end of a polypeptide chain?
A codon that signals the end of a polypeptide chain is called a stop codon. There are three specific stop codons in the genetic code: UAA, UAG, and UGA. When a ribosome encounters one of these codons during translation, it triggers the termination of protein synthesis.
What is the list of stop codons?
Stop codons are specific sequences in messenger RNA that signal the termination of protein synthesis. The three stop codons are UAA, UAG, and UGA. These codons do not code for any amino acids and are recognized by release factors during translation, prompting the release of the newly synthesized polypeptide chain from the ribosome.
How many protein-coding codons are there?
61 codons specify the amino acids used in proteins and 3 codons (stop codons) signal termination of growth of the polypeptide chain...so 64 total
What is the relationship between the linear sequence of codons on mRNA and the linear sequence of amino acids in a polypeptide?
The linear sequence of codons on mRNA corresponds to the linear sequence of amino acids in a polypeptide through the process of translation. Each three-nucleotide codon on the mRNA molecule codes for a specific amino acid, and the sequence of codons determines the order in which amino acids are added to the growing polypeptide chain. This relationship is known as the genetic code.
What codon starts polypeptide synthesis?
The codons are UAA,UAG and UGA

List the amino acids in the order they would appear in the polypeptide coded for by the mRNA?
The order of amino acids in a polypeptide is determined by the sequence of codons in the mRNA. The genetic code determines that specific codons correspond to specific amino acids. The mRNA is read in sets of three nucleotides (codons), each of which codes for an amino acid, resulting in the correct sequence of amino acids in the polypeptide.
What is the list of stop codons?
Stop codons are specific sequences in messenger RNA that signal the termination of protein synthesis. The three stop codons are UAA, UAG, and UGA. These codons do not code for any amino acids and are recognized by release factors during translation, prompting the release of the newly synthesized polypeptide chain from the ribosome.
How many ribosomes are needed for the production of a polypeptide containing thirty amino acids?
One ribosome is needed to synthesize a polypeptide containing thirty amino acids. The ribosome reads the mRNA and assembles the amino acids into a polypeptide chain according to the codons on the mRNA.
Which amino acid chain will these codons form UAA UAG UGA?
The codons UAA, UAG, and UGA are known as stop codons in the genetic code. They do not code for any amino acids but instead signal the termination of protein synthesis. Therefore, these codons will not form an amino acid chain; instead, they indicate the end of a polypeptide sequence during translation.
How do you make a 10 codon sequence for a polypeptide?
To create a 10 codon sequence for a polypeptide, you would need to transcribe a DNA sequence into an mRNA sequence. Each codon consists of three nucleotides. Look for the start codon (AUG) to begin the sequence and then continue adding codons until you have 10 in total.
