2023年11月21日 · A polypeptide chain is a chain of amino acids that is required to make proteins. Proteins are important for structure, signaling, transport, enzymes, and more inside of cells.
Polypeptide Structure, Formation & Examples - Video - Study.com
Let's review. A polypeptide is a chain of amino acids. Amino acids bond together with peptide bonds in order to form a polypeptide. The n-terminal (amino terminal) is located at one end of the ...
What is the difference between an amino acid, a dipeptide, a ...
What makes a polypeptide a protein? Which amino acid always begins a polypeptide (protein) during translation ? What structure is the sequence of amino acids in a protein? a) What do the structures of Glycine and Arginine have in common? b) What makes them different? What connects one amino acid to another in the polypeptide chain?
During the elongation cycle of translation, the A site on a …
The extended polypeptide chain occurs in the E-site in the ribosome. (a) True (b) False. Folding of the polypeptide chain can be performed within a protein complex called a _____. If the protein is NOT folded correctly it can be tagged and degraded …
Define dipeptide, tripeptide, and oligopeptide and polypeptide.
Describe the process a ribosome uses to produce a polypeptide chain. What is meant by the term "secondary structure of an amino acid?" Is galactose a monosaccharide or a disaccharide? Explain. Define antigen, antibody, and agglutination. What does the term codon refer to? What is meant by the term "primary structure of an amino acid"?
What polypeptide is coded for by this mRNA sequence?
The messenger RNA (written as mRNA) is a type of RNA produced during the transcription process of DNA and can code a specific amino acid sequence for a polypeptide molecule. The only thing we must have to write the amino acid sequence of the polypeptide coded by mRNA is the genetic code table that illustrates the equivalent amino acid of each ...
During translation, the ribosome translocates the growing …
During translation, chain elongation continues until _____. a. no further amino acids are needed by the cell b. all tRNAs are empty c. the polypeptide is long enough d. a stop codon is encountered e. the ribosomes run off the end of mRNA; During the process of elongation, polypeptide synthesis takes place.
A peptide bond forms between the amino acid attached to a tRNA …
State whether the following statement is true or false. If the statement is false, modify the statement to make it correct. Polypeptide strand is the active form of a digestive enzyme in the stomach that breaks polypeptide chains into smaller polypeptides; Essential amino acids are obtained only from animal proteins. (a) True (b) False.
