tRNA molecules carry amino acids to the site of protein synthesis

∙ 9y agoIn eukaryotes, tRNA is synthesized in the nucleus. The genome contains tRNA genes in the DNA that are transcribed into pre-tRNA molecules by RNA polymerase III. Further processing within the nucleus produces mature tRNA molecules which then enter the cytoplasm in order to carry out their function of translation.

Why does tRNA have a T shape?
The shape of tRNA is specifically designed to be able to accept the amino acid according to its anticodon. If tRNA was in any other shape, aminoacyl tRNA synthetase, the enzyme that adds amino acid to tRNA, would not be able to transfer the amino acid to tRNA.
Are ribosomes made out of Trna and protein?
tRNA is produced by RNA polymerase III from the nucleus and exported out to the cytoplasm, awaiting for the codon sequence by the mRNA; while mRNA is produced from RNA polymerase II. mRNA comes from the transcription of RNA from the nucleus of the cell, and tRNA follows the same step; but the major difference between mRNA and tRNA is that tRNA uses different RNA polymerase (III), then exported out to the cytoplasm, once the mRNA carries its codon sequence down to the ribosome made up of rRNA (make up ribosomes; also from nucleus, offering one binding site for one mRNA and three sites for tRNA), tRNA carries out the anticodon to the codons. tRNA is produced in the similar process from that of the mRNA and rRNA, only using different polymerases. The anticodon and codon match up, producing polypeptide chains of amino acids, which later become proteins. Another thing to mention, mRNA just writhes away once its sequence is matched up, but tRNA stays in the cytoplasm permanently.
How many binding sites does a ribosome have?
3, the A P E sites(they stand for something but i for got exactly what except for E for exit) A for amino acids entering, P for the amino acids to join together and E for the transport things to E exit
What kind of RNA is an anticodon a part of?
Transfer RNA (tRNA) carries the anticodon.
What happens next after the ribosome reaches the start codon?
tRNA molecules attach to codons.-apex
Are codons found in mRNA or tRNA?
mRNA is made up of anticodons

Cloverleaf structure has mRNA tRNA or rrna?
trna
What are the differences between charged tRNA and uncharged tRNA?
Charged tRNA has an amino acid attached to it, ready for protein synthesis, while uncharged tRNA does not have an amino acid attached. Charged tRNA binds to the appropriate codon on the mRNA during translation, while uncharged tRNA cannot participate in translation.
Where is protein made?
Proteins are made in the ribosomes when the mRNA strand from the nucleus is matched with the anti codon tRNA strand.
Are ribosomes made out of Trna and protein?
tRNA is produced by RNA polymerase III from the nucleus and exported out to the cytoplasm, awaiting for the codon sequence by the mRNA; while mRNA is produced from RNA polymerase II. mRNA comes from the transcription of RNA from the nucleus of the cell, and tRNA follows the same step; but the major difference between mRNA and tRNA is that tRNA uses different RNA polymerase (III), then exported out to the cytoplasm, once the mRNA carries its codon sequence down to the ribosome made up of rRNA (make up ribosomes; also from nucleus, offering one binding site for one mRNA and three sites for tRNA), tRNA carries out the anticodon to the codons. tRNA is produced in the similar process from that of the mRNA and rRNA, only using different polymerases.

Where does the mRMA go after it is made?
mRNA goes out the the ribosome (rRNA) to undergo translation via tRNA
What result would you expect if you mutate one of the four arms of a tRNA?
The tRNA will not be recognized by tRNA synthetase and cannot be charged.
What kind of RNA is an anticodon a part of?
Transfer RNA (tRNA) carries the anticodon.
During translation which type of RNA carries amino acids to ribosomes?
If a molecule of mRNA has AUG as its codon, what anticodon must its complementary tRNA contain?
How many binding sites does a ribosome have?
3, the A P E sites(they stand for something but i for got exactly what except for E for exit) A for amino acids entering, P for the amino acids to join together and E for the transport things to E exit
What is tRNA used during translation?
tRNA (transfer RNA) is used to bring the amino acids to the ribosome when a protein is being made. tRNA has an anticodon that matches with the codon on the mRNA, so that it knows which amino acid to add to the protein that is being created.
