The ribosome has three grooves which are holding sites for the tRNA. The first codon is AUG, called a "start codon". It also codes for the amino acid Met (methionine). So tRNA with the anti-codon sequence of UAC carrying the amino acid Met bonds to the mRNA codon. Another tRNA bonds to the next codon in the next groove with the next respective amino acid. Peptidyl transferase breaks the bond between the tRNA and the first amino acid and then reforms a peptide bond between the first amino acid and the second. This elongation process repeats until a long chain of amino acids is formed, creating a polypeptide. The tRNA exits the ribosome on the "E" site and returns to the cytoplasm. It will then pick up another of the same amino acid from the pool of amino acids stored in the cytoplasm and return to translation.
In two dimensions, tRNA has three loops, one of which is the anti-codon. Opposite the anti-codon is the amino acid attachment site. In three dimensions, tRNA is "L" shaped; bent in the middle. See related links below for images.
What else can I help you with?
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?
Where does the transfer of genetic information from DNA to RNA take place?
The transfer of genetic information from DNA to RNA takes place in the cell nucleus during a process called transcription. Here, an RNA molecule complementary to a specific region of DNA is synthesized by an enzyme called RNA polymerase.
What is the complementary triplet on a transfer RNA molecule?
This triplet is called the anticodon.
What are the 4 types of RNA called?
The four types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), ribosomal RNA (rRNA), and small nuclear RNA (snRNA). Each type plays a specific role in the process of protein synthesis within cells.
Amino acids are picked up by special RNA molecules called?
transfer RNA (tRNA) molecules. These molecules have a specific sequence that matches with the codons on messenger RNA (mRNA) to ensure the correct amino acid is added during protein synthesis.
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?
A RNA that carries amino acids to the growing protein is called?
transfer RNA
Where does the transfer of genetic information from DNA to RNA take place?
The transfer of genetic information from DNA to RNA takes place in the cell nucleus during a process called transcription. Here, an RNA molecule complementary to a specific region of DNA is synthesized by an enzyme called RNA polymerase.
What kind of RNA brings the amino acids to the ribosomes for translation to take place?
This is called transfer RNA. tRNA.
What is the complementary triplet on a transfer RNA molecule?
This triplet is called the anticodon.
Transfer of the genetic message from DNA to messendger RNA is called?
The transfer of the genetic message from DNA to messenger RNA is called transcription. During transcription, an RNA molecule is synthesized by copying a DNA template. This process takes place in the cell's nucleus.
What are the 4 types of RNA called?
The four types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), ribosomal RNA (rRNA), and small nuclear RNA (snRNA). Each type plays a specific role in the process of protein synthesis within cells.
The molecule that contains an anticodon is?
transfer RNA or tRNA
Amino acids are picked up by special RNA molecules called?
transfer RNA (tRNA) molecules. These molecules have a specific sequence that matches with the codons on messenger RNA (mRNA) to ensure the correct amino acid is added during protein synthesis.
When RNA becomes protein the process is called?
RNA does not become protein. Messenger RNA transcribes the DNA code and carries it to a ribosome where it is translated by transfer RNA into a sequence of amino acids that will make a protein. The entire process is called protein synthesis.
What are the 3 different?
transfer RNA messenger RNA Ribosomal RNA
What are molecules that temporarily carry a specific amino acid on the end called?
Transfer RNA
