Nucleotides in the coding region of DNA are transcribed into mRNA.
mRNA, in turn, is translated into a polypeptide via the ribosome.
Three (3) nucleotides correspond to one amino acid. In other words, if the nucleotides in question are AAA, those nucleotides will be transcribed into their mRNA complement, UUU, which in turn will be translated into the amino acid phenylalanine via the ribosome.
Now, if you remove one of those nucleotides, say the first A of the AAA, everything gets screwed up. You get what is caused a frameshift. Say originally you had AAAUAG. As I mentioned, AAA would eventually become phenylalanine, and UAG is a stop codon, which would tell the ribosome to stop translating: the polypeptide is complete. But if the first A of the AAA is removed -- the ribosome still wants to read in threes! So it will read AAU, and code asparagine instead of phenylalanine, and moreover . .. it will keep translating making a polypeptide much longer than evolution intended!
In mature mRNA, there is a start codon (AUG) that instructs ribosome to begin translation. Thereafter, every 3 bases are read as a "code word" calling for a particular amino acid to enlogate the polypeptide chain or to STOP and release the polypeptide. If 1 or 2 nucleotides are deleted or inserted into this sequence, it causes the reading frame to shift. This usually results in misreading of the sequence here is an example: AUG - AGC - ACC - TAA - GGG - etc. (if we delete the first C we get....) AUG - AGA - CCT - AAG - GG ( this is obviously not going to code for the same amino acid sequence)
No, a polypeptide is not an amino acid. A polypeptide is a chain of amino acids linked together by peptide bonds. Amino acids are the building blocks of proteins and are the individual units that make up a polypeptide chain.
Polypeptides are chains of amino acids linked by peptide bonds.
a chain of 25 amino acids can be called a peptide chain ---------------------------------------------------------------------------------- Two or united amino acids form a *dipeptide* Three a *tripeptide* Ten or more a *polypeptide* More than 50 *protine* Therefore a chain of 25 amino acids is a polypeptide :D
Polypeptide chains are produced using messenger RNA (mRNA) as a template during the process of protein synthesis. The mRNA carries the code for the sequence of amino acids that make up the polypeptide chain.
polypeptide chain
Insertion or deletion of nucleotides in DNA can lead to frameshift mutations, in which the reading frame is altered. This can result in a completely different protein being produced, leading to potential changes in the organism's function or traits.
A polypeptide chain is a chain of amino acids, which make up proteins
the answer would be.... polypeptide

A polypeptide chain is a sequence of amino acids that forms the primary structure of a protein. This chain is held together by peptide bonds between adjacent amino acids.
No, a polypeptide is not an amino acid. A polypeptide is a chain of amino acids linked together by peptide bonds. Amino acids are the building blocks of proteins and are the individual units that make up a polypeptide chain.
The protein molecule is called a polypeptide when it consists of a basic chain of amino acids. A polypeptide chain folds into a specific 3D structure to become a functional protein.
Polypeptides are chains of amino acids linked by peptide bonds.
A polypeptide chain is made up amino acids that form from a peptide bond. The polypeptide chain makes up a protein; therefore, the type of protein is contingent on the number of chains present.

A polypeptide chain is a chain of amino acids linked together by peptide bonds. The sequence of amino acids determines the structure and function of the protein formed by the chain.
