What dictates the corresponding sequence of amino acids in a growing polypeptide chain?
The sequence of amino acids being added to the growing polypeptide chain is controlled by the instructions (codons, 3-base codes) on the mRNA. These are a copy of the coding regions of the gene from the DNA in the nucleus.
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 a codon used for?
A codon is a 3-nucleotide sequence which codes for an amino acid. This basically means codons help to form polypeptide changes since each one codes for an amino acid. hope that helps :)
What determines how many amino acids is in a polypeptide?
When a gene is transcribed there is a sequence of RNA bases that was copied from the DNA sequence. The RNA sequence can be exactly the same as the DNA or can be modified more in higher organisms by removing the introns if any. Three RNA bases is a codon. Each codon signifies an amino acid. There is an initiation codon and a terminal codon. So the amino acid sequence is determined by the sequence (multiple of 3 RNA bases) of codons between the initiation codon and termination codon.
What are the nucleotide sequences of tRNA that are complementary to codons on mRNA?
The base sequences on tRNA that are complementary to the codons on mRNA are known as anti-codons. These match up with the codons to ensure the correct amino acid is added to the polypeptide (protein) chain being created. U binds with A, G binds with C.
How do you make a 10 codon sequence for a polypeptide?
A ten codon sequence for a polypeptide is formed when 10 codons. An example would be GGGAAACCCAGAAGGCGACGCCGGCGTNNN are found in an ammino acid linked by an amide bond.

What codon starts polypeptide synthesis?
The codons are UAA,UAG and UGA
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.
How are codons used in polypeptide formation?
Four 'types' of nucleotide bases - when they are read three-at-a-time - this is considered to be a triplet-codon. Triplet codons are individually related to one specific amino acid, a polypeptide being a short protein.
What determines how many amino acids is in a polypeptide?
When a gene is transcribed there is a sequence of RNA bases that was copied from the DNA sequence. The RNA sequence can be exactly the same as the DNA or can be modified more in higher organisms by removing the introns if any. Three RNA bases is a codon. Each codon signifies an amino acid. There is an initiation codon and a terminal codon. So the amino acid sequence is determined by the sequence (multiple of 3 RNA bases) of codons between the initiation codon and termination codon.
What is directly responsible for the sequence of amino acids in a protein?
The sequence of codons in mRNA, or messenger RNA, is most directly responsible for the sequence of amino acids in a protein. Each codon is comprised of 3 nucleotides.
What codon sequence does DNA use?
There are 64 different codons. Refer to the related link for a table of DNA codons.
How many codons are in aaaugcucguaa?
There are four codons in AAA UGC UCG UAA. A codon is a sequence made of three nitrogenous bases. Codons have particular features, making it possible for them to be start codons, stop codons, introns, or exons.
What is the relationship between proteins and DNA?
the DNA copies its base sequence into messenger RNA which carry the information to the transfer RNA which translates it into a sequence of Amino acids.
