What regions of a ribosome holds the growing polypeptide?
The P site and the A site of the ribosome hold the growing polypeptide chain during translation. The P site is where the tRNA carrying the growing polypeptide is located, and the A site is where the new tRNA carrying the next amino acid in the sequence enters.
Does tRNA transfer amino acid during translation or transcription?
tRNA transfers amino acids during translation. Transfer RNA molecules are responsible for bringing amino acids to the ribosome where they are incorporated into a growing polypeptide chain according to the mRNA sequence. Transcription is the process of synthesizing mRNA from DNA, and tRNA is not directly involved in this process.
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.
One binding site on a ribosome holds an mRNA molecule and the other two binding?
sites hold tRNA molecules. The mRNA binding site is where the mRNA molecule binds and is read during translation. The tRNA binding sites are where tRNAs carrying amino acids bind and deliver them 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.
When does the polypeptide stop growing?
The polypeptide stops growing when it reaches a stop codon on the mRNA during translation. This signals the ribosome to release the polypeptide chain, which then undergoes further processing to become a functional protein.
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.
When the ribosome moves to the right what happens to the first tRNA molecule?
The first tRNA molecule is released as the ribosome moves to the right during translation. It is no longer needed once it has delivered its amino acid to the growing polypeptide chain.
What regions of a ribosome holds the growing polypeptide?
The P site and the A site of the ribosome hold the growing polypeptide chain during translation. The P site is where the tRNA carrying the growing polypeptide is located, and the A site is where the new tRNA carrying the next amino acid in the sequence enters.
What is the role of the tRNA anticodon?
the tRNA carries only the amino acid that the anti-codon specifies. for example: one tRNA molecule for the amino acid cysteine has an anticodon of ACA. this anticodon binds to thh mRNA codon UGU.
Does tRNA transfer amino acid during translation or transcription?
tRNA transfers amino acids during translation. Transfer RNA molecules are responsible for bringing amino acids to the ribosome where they are incorporated into a growing polypeptide chain according to the mRNA sequence. Transcription is the process of synthesizing mRNA from DNA, and tRNA is not directly involved in this process.
The step of translation in which amino acids are added one at a time to the growing polypeptide is?
The step of translation in which amino acids are added one at a time to the growing polypeptide is called elongation. During elongation, transfer RNA (tRNA) molecules carrying amino acids enter the ribosome and add their amino acids to the growing chain in a sequence determined by the mRNA codons.
At one end of a tRNA molecule there exists a short tail. This tail?
is responsible for binding with the corresponding mRNA codon during the process of translation. It helps to ensure that the correct amino acid is added to the growing polypeptide chain.
What is used during RNA translation.?
mRNA- a transcript of DNA which serves as instuctions for polypeptide formation. amino acid- a single buildin block of protein. tRNA- a molecule that carries a specific amino acid and recognizes its complementary base sequence on an mRNA strand. ribosome- an organelle which serves as the "factory" where amino acids are addes to a growing polypeptide chain.
