What is added to the polypeptide strand?
Amino acids are added to the growing polypeptide strand during protein synthesis. Ribosomes facilitate the process by reading the mRNA and catalyzing the formation of peptide bonds between the amino acids. This results in the elongation of the polypeptide chain until a stop codon is reached.
Describr the role of tRNA in translation?
tRNA (transfer RNA) plays a crucial role in translation by carrying specific amino acids to the ribosome where they are added to the growing polypeptide chain. Each tRNA molecule has an anticodon that base pairs with the complementary codon on the mRNA, ensuring that the correct amino acid is added to the chain. This process is essential for the accurate synthesis of proteins in the cell.
What is the propose of tRNA?
Transfer RNA (tRNA) plays a crucial role in protein synthesis in cells. It carries specific amino acids to the ribosome during translation, where they are added to the growing polypeptide chain according to the codons on the mRNA.
When is the new Amino acid added to the polypeptide chain?
The new amino acid is added to the polypeptide chain during the elongation phase of translation. This occurs when the ribosome reads the mRNA codon and brings in the corresponding tRNA with the attached amino acid. The amino acid is then added to the growing polypeptide chain through peptide bond formation.
What takes place during initiation translation and termination?
During initiation of translation, the ribosome assembles around the mRNA, and the first tRNA, carrying the start codon (usually AUG), binds to the P site of the ribosome. In the elongation phase, amino acids are sequentially added to the growing polypeptide chain as tRNAs bring corresponding amino acids to the ribosome. Termination occurs when a stop codon (UAA, UAG, or UGA) is reached, prompting the release factor to bind, which catalyzes the release of the completed polypeptide and disassembly of the ribosomal complex.

What is the purpose of a transfer RNA?
Transfer RNA (tRNA) plays a crucial role in protein synthesis by carrying specific amino acids to the ribosome during translation. Each tRNA molecule has an anticodon region that binds to the corresponding codon on messenger RNA, ensuring that the correct amino acid is added to the growing polypeptide chain.
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 is the role Trna During translation?
tRNA (transfer RNA) carries specific amino acids to the ribosome during translation. It recognizes the codons on mRNA with its anticodon, ensuring the correct amino acid is added to the growing polypeptide chain. Overall, tRNA plays a crucial role in protein synthesis by translating the genetic code from mRNA into a specific amino acid sequence.
When is the new Amino acid added to the polypeptide chain?
The new amino acid is added to the polypeptide chain during the elongation phase of translation. This occurs when the ribosome reads the mRNA codon and brings in the corresponding tRNA with the attached amino acid. The amino acid is then added to the growing polypeptide chain through peptide bond formation.
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.
What takes place during initiation translation and termination?
During initiation of translation, the ribosome assembles around the mRNA, and the first tRNA, carrying the start codon (usually AUG), binds to the P site of the ribosome. In the elongation phase, amino acids are sequentially added to the growing polypeptide chain as tRNAs bring corresponding amino acids to the ribosome. Termination occurs when a stop codon (UAA, UAG, or UGA) is reached, prompting the release factor to bind, which catalyzes the release of the completed polypeptide and disassembly of the ribosomal complex.

What is the role of tRNA durning translation?
tRNA, or transfer RNA, plays a crucial role in translation by bringing amino acids to the ribosome. Each tRNA molecule carries a specific amino acid and has an anticodon that can base pair with the codon on the mRNA. This allows for the accurate incorporation of amino acids into the growing polypeptide chain.
Which kind of RNA has an anticodon region and carries the amino acids to the ribosome?
Transfer RNA (tRNA) has an anticodon region that base pairs with the codon on mRNA during translation. tRNA also carries specific amino acids to the ribosome according to the genetic code, where they are added to the growing polypeptide chain.
