tRNA has the following sequence in its anticodon: 5'-GCT-3'. Which amino acid should be attached to this tRNA? ATG
As the sequence is read from 3'-5' but here the sequence is given fro 5'-3' which is in an opposite manner so first write it as 3'-TCG-' then amino acid which attached with the code is AGC which code for serine amino acid. Hence the answer is Serine
There is a mutation in the tRNA anticodon since it has a sequence of 5'- UUA-3' but the regular tRNA anticodon sequence is 5'- AAA-3'. Does the mutation have an effect on translation? Explain if it would affect the proteins, how, and if all proteins would be affected.
a.
On the right is the structure of a tRNA
molecule. Which of the following is
the anticodon sequence (from 3’ to 5’)
of this tRNA?
b.
Refer to the sequence of the tRNA molecule in Question 1 above
and the codon table, what is the codon sequence (from 5’ to 3’) on
the messenger RNA and which
amino acid is attached to this tRNA?
5
A codon for the amino acid alanine is GCA. Therefore, the anticodon sequence on the tRNA that brings alanine to the ribosome will be: CGU ACG GCA TGC
Suppose it was possible to change the anticodon on a tRNA from 3-CCG-5'to 3-UGG- 5' after the amino acid was already loaded. Predict the result in a translated polypeptide. What if you changed the sequence prior to the amino acid being loaded onto the tRNA? O In the first case glycine would be found in the polypeptide where threonine was supposed to be. In the second case the changed tRNA would behave like a tRNA for threonine. O In the...
What amino acid is attached to a tRNA with the following anticodon: 5' GCA 3'? SECOND POSITION с A U phenyl- alanine tyrosine cysteine U serine U с A leucine stop stop tryptophan stop G histidine U с A с leucine proline arginine FIRST POSITION glutamine THIRD POSITION G U isoleucine asparagine serine A threonine A lysine arginine methionine G U с A valine G aspartic acid glutamic acid alanine glycine and start Cysteine Alanine Arginine Serine
A tRNA with the anticodon 5'-CCC-3' would carry the amino acid: Select one: a. Phenylalanine b. It would not carry an amino acid c. Proline d. Glycine
During elongation of proteins during protein synthesis tRNA with the amino acid that matches its anticodon binds to the codon on the mRNA. each new amino acid is first transferred to the anticodon of the tRNA. anticodons on the ribosomes recognize the codons on the mRNA and attach the correct amino acids. ribosomes move along the DNA. RNA polymerase II uses the codons on the mRNA to polymerize the protein.
What is the anticodon sequence of the tRNA that binds to the fourth codon of this mRNA? mRNA sequence: ‘5 AUG UUU CUC CUA GGC UGG AGU UGA 3’
Question 43 Not yet answered The sequence below is the anticodon of a tRNA molecule. What amino acid do you expect to find bound to the tRNA? Use the 3 letter code for the aminoacid name (i.e gly for glycine), case is not important. 5-tcg-3 Points out of 2.50 P Flag question Answer: Question 44 Not yet answered Points out of 2.50 If a base is misread, and in consequence, the wrong nucleotide is written in the nascent DNA strand,...
Q.N.6) 5'AUGAAACAGGCGUAA3' is a short mRNA sequence . The anticodon of the tRNA that attaches to the first codon will be?
