Yes, an amino acid can be used multiple times in the sequence of a protein. Proteins are made up of 20 different amino acids, which can be repeated in various combinations and lengths to form the unique sequence of each protein.

A mutation that alters a single amino acid within a protein can alter?
The structure and function of the protein, potentially leading to changes in its overall properties and interactions with other molecules. This can impact the protein's stability, activity, and ability to carry out its function effectively.
What do transfer RNA molecules do during protein synthesis?
Transfer RNA (tRNA) molecules carry specific amino acids to the ribosome during protein synthesis. Each tRNA molecule has an anticodon that base pairs with the complementary codon on the mRNA, ensuring the correct amino acid is added to the growing polypeptide chain.
How many bases make up the code for one amino acid?
There are 3 nitrogen bases equalling one amino acid and they are called codons. Amino acids are the building blocks of protein and in turn protein in science is one of the building blocks of life. The protein molecule has the chromosome strands. On each strand of the chromosome there are shapes in groups of 3 which is the RNA or the Ribonucleic Acid. Where the chromosomes are located, the strands have messengers that travel outside to the ribosomes to be decoded or decyphered. Once the RNA has been decoded by the ribosomes the amino acid is formed. The chronological order of the amino acid being decyphered determines the type of protein. Protein is essential for human growth as it helps with the repair of our muscles amoungst many of it's uses.
Pepsinogen- what does the extra 44 amino acids do?
The extra 44 amino acids in pepsinogen act as a signal sequence that helps target the protein to the secretory pathway in the cell. Once inside the stomach, pepsinogen is converted to pepsin by removing this signal sequence, allowing it to function in protein digestion.
What do you call a chain of 25 amino acids?
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
The DNA base sequence GGG codes for the amino acid proline. Could this same base sequence code for a different amino acid Why or why not?
Yes because once an amino acid is added to the protein chain, the transfer RNA is released into the cytoplasm and can pick up another amino acid.
A mutation that alters a single amino acid within a protein can alter?
The structure and function of the protein, potentially leading to changes in its overall properties and interactions with other molecules. This can impact the protein's stability, activity, and ability to carry out its function effectively.
During protein synthesis what happens to amino acids?
Amino acids are linked together in a specific sequence based on the instructions from mRNA during protein synthesis. Once the correct amino acid sequence is assembled, it folds into a functional protein with a specific structure and function. Any errors in the amino acid sequence can lead to misfolded proteins or protein dysfunction.
What happens to amino acids once they arrive in a cell?
Once amino acids arrive in a cell, they are utilized for protein synthesis. Ribosomes in the cell read the sequence of messenger RNA (mRNA) to assemble amino acids into specific protein structures according to the genetic code. Each amino acid is incorporated into the growing protein chain until the entire protein is synthesized.
What do transfer RNA molecules do during protein synthesis?
Transfer RNA (tRNA) molecules carry specific amino acids to the ribosome during protein synthesis. Each tRNA molecule has an anticodon that base pairs with the complementary codon on the mRNA, ensuring the correct amino acid is added to the growing polypeptide chain.

The DNA base sequence GGG codes for the amino acid proline. could this same base sequence code for a different amino acid?
No, in the genetic code, each three-nucleotide sequence (codon) corresponds to a specific amino acid, and it is specific and unambiguous. GGG will always encode for proline and cannot code for any other amino acid.
Can you take 3 Amino 1000 pills at once?
Yes! That only equates to 30g of protein (in simplified amino acid form), you could take 30 of them and be taking the equivalent of most gym goers post workout shakes.
How does polypeptide differ than an equal protein?
Both peptides and proteins are made up of strings of the body's basic building blocks – amino acids – and held together by peptide bonds. In basic terms, the difference is that peptides are made up of smaller chains of amino acids than proteins. ... As a general rule, a peptide contains two or more amino acids.
How does aminoacyl-tRNA synthesis work?
During aminoacyl-tRNA synthesis, an amino acid is activated by an aminoacyl-tRNA synthetase enzyme, forming an aminoacyl-AMP intermediate. This intermediate transfers the amino acid to the 3' end of a tRNA molecule, creating an aminoacyl-tRNA complex that is ready for protein synthesis in the ribosome. Each aminoacyl-tRNA synthetase is specific to a particular amino acid.
What is the end product of proteins?
amino acids
