What is the sequence of events in translation?
1 ribosomes bind to mRNA 2 Amino acid-carrying tRNA molecules bind to mRNA 3 the polypeptide elongates as new amino acids are added 4 a stop codon on the mRNA is reached 5 the polypeptide is released 6 the ribosomes dissociate from the mRNA plato=C
What does tRNA anticodon bind with?
In normal conditions C always Paris with G and A with U in mRNA so in this CAG the anticoodon wil be GUC
How is the placement of the amino acid during translation is determined by the?
During the translation process, the translation machinery reads the sequence of nucleotides present on the mRNA. The sequence of nucleotides on mRNA is divided in codons, these are set of three nucleotides. There are total 64 codons that contiguously present on mRNA. corresponding to each mRNA codon there is a tRNA that has an anticodon loop that has three nucleotide complementary to the codon. Now Anticodons bind to their specific amino acid called as the charging of the tRNA and carry to the mRNA that is bound to ribosome. The catalytic activity of the 16s rRNA leds to the formation of peptide bond between the coming and the already added amino acid.
What is the difference between codon and anticodon?
A codon is the triplet sequence in the messenger RNA (mRNA) transcript which specifies a corresponding amino acid (or a start or stop command). An anticodon is the corresponding triplet sequence on the transfer RNA (tRNA) which brings in the specific amino acid to the ribosome during translation. The anticodon is complementary to the codon, that is, if the codon is AUU, then the anticodon is UAA. There are no T (Thymine) nitrogen bases in mRNA. It's replaced by U (Uracil).
What is the importance of the codons in protein synthesis?
A codon is the triplet sequence in the messenger RNA (mRNA) transcript which specifies a corresponding amino acid (or a start or stop command). An anticodon is the corresponding triplet sequence on the transfer RNA (tRNA) which brings in the specifieds amino acid to the ribosome during translation. The anticodon is complementary to the codon, that is, if the codon is AUU, then the anticodon is UAA. No Thymine's in mRNA. It's replaced by Uranine
How does the termination of translation occur?
The termination of protein translation is caused by termination codon. Termination happens when a stop codon is reached, there is no amino acid to be incorporated and the entire assembly releases the newly synthesized polypeptide.
Does tRNA have anti-codons?
"The mechanism in which a release factor recognizes a stop codon is still unknown." Since anticodons are normally on the complementary tRNA. (The tRNA is what 'reads' the codons on the mRNA and ferries in the corresponding amino acid.) During translation stop codons are recognized by "release factors" that bind to the A-site on the ribosomes during translation.

What are the steps taken to translate a 9-base DNA strand into an amino acid sequence?
There are a huge number of steps involved in this process, but briefly it goes like this: # Transcription factors bind to DNA and promote binding of RNA polymerase # RNA polymerase binds in complex with transcription factors # Transcription is initiated and RNA polymerase uses free NTPs, complementary to the antisense strand of DNA to create an RNA copy of the DNA. # The mRNA leaves the nucleus - some modification may take place # Translation factors bind mRNA # Ribosome binds to mRNA # tRNA brings amino acids to ribosome # Ribosome begins translation at methionine start codon - matching anticodon on tRNA to triplet codons on mRNA to pair correct amino acid to the mRNA code # Ribosome stops translation at stop codon # Ribosome/mRNA/tripeptide complex will dissociate

Why do you have stop codons that signal the end of the amino acid chain?
A stop codon signals a termination of translation - in other words that the protein being built from the amino acid instructions is complete. They bind "release" factors that allow the completed protein to come away from the template.
What are the differences between codon anticodon?
Codons are three bases on mRNA which go to the ribosome which translates into amino acids. The amino acids are attached to tRNA which has the anticodon on it which will bind to the codon on the mRNA. This is how the ribosome picks out the correct amino acid. the tRNA with the anti codon just binds to the codon and the amino acids start binding together via peptide bonds.
Briefly describe how the process of translation is started?
In the cytoplasm, rRNA binds to the "start" codon of a mRNA molecule. Next, a tRNA molecule with the complimentary anticodon binds to the mRNA start codon and releases an amino acid. As the mRNA moves through the rRNA, new tRNA's come along and bind to the mRNA, adding a new amino acid each time. Eventually a "stop" codon is reached, and the rRNA, mRNA, and tRNA break apart, releasing a long chain of amino acids which will fold into a protein.

How does an anticodon compare to a codon?
The anticodon is a sequence of three unpaired nucleotides in transfer RNA, which can bind through base pairing, to the complementary triplet of nucleotides, or codon in a messenger RNA molecule. The codon makes up the genetic code, the anticodon makes the amino acid.
